A Digital Oscilloscope has New Age Technology
We have tested Digital Oscilloscopes fully for compatibility and performance impact. Because some oscilloscope users may prefer another tool for this purpose, or may be planning to use their oscilloscope in standalone mode, trial installer on the desktop oscilloscopes.
If an oscilloscope protected with Antivirus has been disconnected from the network for an extended period, we recommend updating the virus definition files manually using a CD or USB memory stick before reconnecting the instrument to a network. Since it is possible you may receive a digital oscilloscope from storage or in transit for some period, we recommend routine application of critical OS patches as part of your regular oscilloscope maintenance.
Your digital oscilloscope is expected to provide long service life and therefore your recovery partition does age. If you find it necessary to rebuild an older oscilloscope, service packs and critical updates must also be reinstalled.
The information age, also commonly known as the computer age or digital age, is an idea that the current age will be characterized by the ability of individuals to transfer information freely, and to have instant access to knowledge that would have been difficult or impossible to find previously. The idea is linked to the concept of a digital age or digital revolution, and carries the ramifications of a shift from traditional industry that the industrial revolution brought through industrialization, to an economy based on the manipulation of information, i.e., an information society.
One of the major things that have helped automobiles to provide more safety and convenience, though, is electronics. Not only does this new technology prevent the engine from flooding by allowing too much fuel into the engine, but it is also more efficient and emission-friendly such as digital oscilloscopes, a digital volt-ohm meter, sensor stimulators and high-tech computers to determine problems. It also requires extensive knowledge about how to use the technology. Mechanics often need to go through training to use this method.

PC Oscilloscope is Very User Friendly
Oscilloscopes play a very important role in the design & development of various electronic systems. The current market is flooded with a host of oscilloscopes, however there are very few that are affordable & user friendly. User friendly file system always built-in digital oscilloscopes, so you can store what you want in the flash drive or download to your computer.
PC Oscilloscopes use the PCs you already own so give large color displays (so the whole class can see) and the ability to save and print waveforms. Data can easily be exported to other Windows applications for further analysis or for writing reports.
All the required software is included with the products, there are no licensing requirements — you can use the software on as many PCs as you like, and free software updates are available from our website. Most PC oscilloscopes are limited to the capture of a few million points of information, which is useful for human eye analysis, they offer little to no custom programming options, produce low dynamic range data and are not always easy to control or transfer data from within an embedded environment. PC based oscilloscopes offer a cost effective and portable solution for traditional bench-top oscilloscopes.
A new type of "oscilloscope" is emerging that consists of a specialized signal acquisition board which can be an external USB or Parallel port device or an internal add-on PCI or ISA card. The chief benefit of a quality oscilloscope is the quality of the trigger circuit. If the trigger is unstable, the display will always be fuzzy. The quality improves roughly as the frequency response and voltage stability of the trigger increase.

Digital Multimeters Are Easy to Carry and Use
A multimeter or a multitester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability to measure voltage, current and resistance.
Multimeters may use analog or digital circuits—analog multimeters (AMM) and digital multimeters (often abbreviated DMM or DVOM.) Analog instruments are usually based on a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made; digital instruments usually display digits, but may display a bar of a length proportional to the quantity being measured.
Modern multimeters are often digital due to their accuracy, durability and extra features. In a digital multimeter the signal under test is converted to a voltage and an amplifier with electronically controlled gain preconditions the signal. A digital multimeter displays the quantity measured as a number, which eliminates parallax errors. To begin using the digital multi-meter, you must place the test probes in their proper receptacles. The common probe (black) is placed into the COM (common) position.
You will notice that the selection dial is pointing within the resistance section - in particular, the dial is currently pointing to the continuity position. In this position, when continuity (any resistance) is detected, the digital multi-meter will emit an electronic bell sound.Digital multimeter you can make voltage, current, resistance, frequency, period, capacitance and temperature measurements with confidence.You can also monitor and record measurements over time or environmental ranges and view statistical values to see how your circuit's performance is changing. And, dedicated front-panel buttons provide fast access to frequently used functions and parameters, reducing set up time.
Each Hantek digital multimeter provides the feature-rich tools and precision you need for your most demanding measurements. Some digital multimeters are designed to provide the exact readings of the multimeter, while other multimeters provide percentages for an easier reading, according to Fluke. However, the percentages do not always give the tester enough details to make a diagnosis based on the readings. Many digital multimeters come with protection mechanisms that are designed to protect the digital multimeter from over voltages.

Logic Analyzer is Simple and Powerful
A logic analyzer is an electronic instrument which displays signals in a digital circuit. A logic analyzer may convert the captured data into timing diagrams, protocol decodes, state machine traces, assembly language, or correlate assembly with source-level software.
Once the probes are connected, the user programs the analyzer with the names of each signal, and can group several signals together for easier manipulation. Next, a capture mode is chosen, either timing mode, where the input signals are sampled at regular intervals based on an internal or external clock source, or state mode, where one or more of the signals are defined as "clocks," and data is taken on the rising or falling edges of these clocks, optionally using other signals to qualify these clocks. Many digital designs, including those of ICs, are simulated to detect defects before the unit is constructed. The simulation usually provides logic analysis displays.
Often, complex discrete logic is verified by simulating inputs and testing outputs using boundary scan. Logic analyzers can uncover hardware defects that are not found in simulation. These problems are typically too difficult to model in simulation, or too time consuming to simulate and often cross multiple clock domains.
With a Logic Analyzer, you can acquire fast edges with the industry's highest acquisition speed. Support packages tuned to your specific application makes it easier for you to probe, acquire, decode, analyze, and validate the performance of your microprocessor, FPGA or memory design.

Arbitrary Waveform Generator is the New Age Machine
Arbitrary waveform generators, or AWGs, are sophisticated signal generators which allow the user to generate arbitrary waveforms, within published limits of frequency range, accuracy, and output level. Unlike function generators, which are limited to a simple set of waveforms; an AWG allows the user to specify a source waveform in a variety of different ways. AWGs are generally more expensive than function generators, and are often more highly limited in available bandwidth; as a result, they are generally limited to higher-end design and test applications.
An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resulting waveforms can be injected into a device under test and analyzed as they progress through the device, confirming the proper operation of the device or pinpointing a fault in the device.
Unlike function generators, AWGs can generate any arbitrarily defined wave shape as their output. The waveform is usually defined as a series of "waypoints" (specific voltage targets occurring at specific times along the waveform) and the AWG can either jump to those levels or use any of several methods to interpolate between those levels.
An arbitrary waveform generator (AWG) is an advanced signal generator that can generate a waveform of almost any shape. The generated waveform can then be inserted into the device you wish to test and then analyzed as it progresses through the device to confirm correct operation, or to highlight a fault.
Arbitrary waveform generators are often expensive and so are usually only found in high–end test equipment, however, several PC Oscilloscopes include a built–in AWG. The arbitrary waveform generator is programmed with a data file, supplied by the user, which defines the output voltage at a number of equally spaced points in time. The circuit uses this data to reconstruct the waveform with a specified amplitude and frequency.
Arbitrary waveform generators, or AWGs, are sophisticated signal generators which allow the user to generate arbitrary waveforms, within published limits of frequency range, accuracy, and output level. Unlike function generators, which are limited to a simple set of waveforms; an AWG allows the user to specify a source waveform in a variety of different ways. AWGs are generally more expensive than function generators, and are often more highly limited in available bandwidth; as a result, they are generally limited to higher-end design and test applications.
An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resulting waveforms can be injected into a device under test and analyzed as they progress through the device, confirming the proper operation of the device or pinpointing a fault in the device.
Unlike function generators, AWGs can generate any arbitrarily defined wave shape as their output. The waveform is usually defined as a series of "waypoints" (specific voltage targets occurring at specific times along the waveform) and the AWG can either jump to those levels or use any of several methods to interpolate between those levels.
An arbitrary waveform generator (AWG) is an advanced signal generator that can generate a waveform of almost any shape. The generated waveform can then be inserted into the device you wish to test and then analyzed as it progresses through the device to confirm correct operation, or to highlight a fault.
Arbitrary waveform generators are often expensive and so are usually only found in high–end test equipment, however, several PC Oscilloscopes include a built–in AWG. The arbitrary waveform generator is programmed with a data file, supplied by the user, which defines the output voltage at a number of equally spaced points in time. The circuit uses this data to reconstruct the waveform with a specified amplitude and frequency.

Digital Oscilloscope is Useful in Every Field
The digital oscilloscope is an indispensable tool for anyone designing, manufacturing or repairing electronic equipment. In today's fast-paced world, engineers need the best tools available to solve their measurement challenges quickly and accurately.
As the eyes of the engineer, digital oscilloscopes (DSO) are the key to meeting today's demanding measurement challenges. The usefulness of a digital oscilloscope is not limited to the world of electronics. With the proper sensor, a digital oscilloscope can measure all kinds of phenomena. A sensor is a device that creates an electrical signal in response to physical stimuli, such as sound, mechanical stress, pressure, light, or heat. A microphone is a sensor that converts sound into an electrical signal.
DSO oscilloscopes are used by everyone from physicists to repair technicians. An automotive engineer uses a digital oscilloscope to correlate analog data from sensors with serial data from the engine control unit. A medical researcher uses a digital oscilloscope to measure brain waves. The possibilities are endless.
A digital phosphor Oscilloscope (DPO) is a digital oscilloscope but instead of a CRT, it uses a digital flat panel display, usually a liquid crystal panel. These are becoming the de facto digital oscilloscope system. With the relentless march of technological progress: DPOs can offer significant enhancements over traditional oscilloscopes, such as different color traces for different inputs or signal types or even parts of the displayed signal. Also a DPO can emulate long persistence phosphors in traditional CRT systems. Many designs can also provide near real time information on the displayed waveform such as amplitude (including average; peak; peak to peak; and RMS), repetition rate and even more complex functions such as flourier transforms.
Digital oscilloscopes have many advantages over its analog counterpart, like the ability to capture single events, and to display what happens before the trigger. You also can build a digital oscilloscope simply by hooking an ADC and an FPGA together.

How to Use A Digital Multimeter To Test A Resistor
Digital multimeter is a necessary tool for electricians. The most advantage of it is can test components. This article is going to explain how to use a digital multimeter to test a resistor.
Resistors are components which to limit the current to other components. Ohm is used to calculated resistor.
Instructions
1. Connect the black probe to the “COM” and connect the red probe to the port “ohm”.
2. You can use alligator clips to attach the probes of digital multimeter. The alligator clips is provide a better connection to the component and match the probes.
3. Make a connection with the each terminal of the resistor use the alligator clips. There are four color band types with the common resistors. The first two colors express values, and the third one is express a multiplier, and the fourth band express the difference of the resistor value. Theoretically, this resistor should with 2700 Ohm with 5% deviation of the value. That is to say the better resistor, the lower deviation. General speaking, 5% deviation is a symbol of the good resistor.
4. Dial your digital multimeter to the Ohms. Small part of the dear digital multimeters has the setting with the multiplier, such as x100, x 1000. However, digital multimeter will auto set the multiplier, so you can read the results directly.
5. When you take your digital multimeter reading, you can estimate the value, you can subtract 5% deviation, you can get the real reading.
6. You should make sure there is no voltage active in circuit. You can touch either terminal with your digital multimeter probes.
7. The resistor should have the value of 510 ohms. If your digital multimeter shows the value of resistor is 509, that is to say it is a good resistor.

the Use and Caution of
Digital Multimeter
Now, measuring instruments of digital have become a mainstream in our daily life. It is also a trend to replace measuring instruments of analog. Compared with analog multimeters, digital multimeters have many advantages, including a high sensitivity, a high accuracy, strong overload capacity, easy to carry and so on.
(1) Use
a, Before using, we should read the instruction manual carefully, know well the power switch, range switch, jacks, the effect of the special jacks.
b, Transferred the power switch to the “ON” position.
c, The measurement of AC and DC voltage: according to the needs to switch in the appropriate range of DC or AC. Then made the red pen insert V/Ω and the black pen insert COM hole. The multimeter should in parallel with the test line. So it can read out automatically.
d, The measurement of AC or DC current: transferred the range switch to the appropriate range of DC or AC. The red pen should insert mA hole (<200mA) or 10A holes (> 200mA), and the black pen insert COM hole. Then the digital multimeter should in series with the test circuit. When testing the DC, digital multimeter will display polarity automatically.
e, The measurements of resistance: transferred the range switch to appropriate position of Ω. The red pen insert V / Ω hole, and the black pen insert COM hole. When tested resistance exceeds the maximum value of the selected range, digital multimeter will display "1", so we should select a higher range. When measuring the resistance, the red pen stands positive and the black stands negative. This is not the same with analog multimeter. Therefore, when we measuring transistors, electrolytic capacitors and other components which are have polarity, we should pay attention to the polarity of meter pen.
(2). Caution
a, If we can’t certain the size of the voltage or current, we should set the maximum range. Then we reduce gradually the range to appropriate position. After testing, we should transfer the range switch to the highest voltage profile and turn off the power.
b, when the multimeter display “1”, we should choose a higher range.
c, When measuring the voltage, digital multimeter should in parallel with the circuit. When measuring the current, it should in series with the circuit, this time we can ignore the polarity of positive or negative.
d, When we misuse voltage profile of AC to measure DC current, or misuse DC voltage profile to measure AC voltage, the screen will show"000", or low numbers starting to beat.
e, Forbid to change the range when measuring the high voltage (over 220V) or high (over 0.5A), avoid to burning switch contacts which on digital multimeter.

Digital Multimeter can Determine the Breakpoint
Digital multimeters not only can measure voltage, current, resistance, capacitors, transistors and other basic parameters, but also through the alternative use can expand the functions of it, then make itself into a multi-function meter.
Today, I am going to introduce a way of how to determine the breakpoint of the wire or cable.
When there some breaks with wire or cable, as the external package of the wire or cable have insulations, so to determine the exact location of the breakpoint is very hard. We can use digital multimeter to help us solve the problem. The specific methods are as follow: put one side of the wire or cable that has breakpoint connected to the firing line of 220V, and put the other side floating in the air. We can set the digital multimeter in the AC-2V profile, from the access side of firing line to started, one hand hold on the point of the black meter pen, the other hand hold the red meter pen move on the external insulation of the wire or cable’s package, this time, the value of voltage displays about 0.445V. If the red meter pen move on to someplace which the voltage is suddenly dropped to 0.0 a few volts which display on the screen, so we can certain the location of the breakpoint is forward 15cm along the access side which on the firing line.
If use this way to check shield, it will no use in this situation that is only wire broken and shield package is not broken.
If your job is always facing to check the circuit or determine the breakpoint of wire or cable, you might need a handheld digital multimeter. Recommend you go to youroscilloscope.com have a look. You may find right one with high quality and cheap price.

Digital Multimeter
and Analog Multimeter
Multimeter, we know as a tool which used to measure DC current, DC voltage, AC current, AC voltage, resistance and audio equality. Some of them are used to measure some parameters of AC current, capacitance, inductance and semiconductor. People didn’t know how to use a multimeter in a few decades ago, except engineers. But now, multimeter as a commonly used tool in everyone’s daily life, it is no longer for engineers dedicated.
Multimeters are divided into types. One is analog model, another one is digital model. We often called the digital model as the digital multimeter, the analog model as the analog mulitmeter. Digital multimeter displays the results in numbers, but analog one indicates the value with a needle over a scale.
Here, I am going to tell the tips about how to choose a digital multimeter or analog multimeter.
Firstly, the accuracy of the analog multimeter is poor, but the process of the pointers swing is relatively straightforward. Sometimes this range of swing speed reflects objectively the size of what be measured. Reading of digital multimeter will be intuitively, but the changes of the figures looks very messy. It is not easy to observe.
Secondly, generally speaking the pointer table has two batteries which is a low voltage 1.5V and a high voltage 9V or 15V. The black meter pen is positive side which is relative to the red one. However, digital multimeter often uses a battery of 6V or 9V.
Thirdly, when in the voltage profile, the internal resistance of analog multimeter is smaller than digital multimeter one, and the accuracy of analog one is less than the digital one. However, the resistance of digital one is at least in meohm level. It has little effect on the test circuit. But it is easy affected by extremely high output impedance. So the test status may be virtual in the situations which are stronger electromagnetic.
In a word, analog multimeters are suit for measuring analog circuit which is high current or high voltage, such as TV, audio amplifier. However, digital multimeters are suit for digital circuit which is low voltage and low current, such as BP machines, mobile phones. Of course, it is not absolute, you can depend on specific situations to choose which one.
If you are interested in digital multimeters, you might want to buy a high quality and cheap price digital one, highly recommend you view youroscilloscope.com.

The Use and Maintenance
of Digital Multimeter
Firstly, turn on the power of digital multimeter and select the test object such as voltage, current, resistance or other object. Secondly, determine the range, when we are unsure the range, we can set the range to maximum, then gradually reduce the maximum range. Before testing, we should check the meter pen whether in the correct hole. When we toggle the range switch, the force should be appropriate, avoiding the damage to metal switch. After testing, rotary switch should be in the high voltage profile.
Some explanations during the testing of digital multimeters:
(1) For the high impedance profile, the test results of resistance is different from the test results of pointer table. The slightly difference is due to the test conditions.
(2) When testing the physical quantity which is related to the polarity, whose polarity should be corresponded to the meter pen. That is to say when not display the polarity, the point of the red meter pen shows potential is in high-end or the side which is the current into. When the polarity shows“-”, so the point of the red meter pen is in low-end potential or the side which is the current out.
(3) Resistance profile and diode profile are different from the pointer meter pen. When the pointer meter pen testing the resistance, the red pen and black pen are opposite to the polarity, that is to say black stands positive electrode, red stands negative electrode. However, the polarity of digital multimeter is the same with test source. Red pen stands positive electrode, black pen stands negative electrode. These are the same with voltage and current. It will not be confused. So it is superior than the pointer meter.
(4) When we don’t know the polarity or don’t know the pin order of the transistor, we can identify and certain every polarity of the transistor by times for foot using the hfe profile of transistor.
(5) Calibration
Digital multimeter should be calibrated regularly. When we are calibrating it, we should choose a similar one or a higher accuracy digital meter. The calibrated order as following: first, DC profile; second, AC profile; third, capacitance profile.
General, digital multimeter uses a 9V laminated battery, often use for a few months. Recommend you to buy a 9V rechargeable battery to have a replacement. So it can save your money.

In this program, waveform data are in real-time collected, pulse the advantage which is easy to process the data on the PC,so the real-time collected waveform data will convert to the data that is needed during the measure.
According to the master control program running on PC,making the hardware control and data process together, unified by an external control. First, the waveform data of exposure current is collected by virtual oscilloscope, the module of data collection is connected with PC by USB port. Then the real-time collection data is passed to the PC by the USB port, PC is communicating with external hardware modules by USB low level drivers of the virtual oscilloscope. PC process software takes advantage of PC whose quickly process capability to process data, get the peak, and restore the real-time waveform.

Digital Storage Oscilloscope
Digital storage oscilloscope (DSO) can help you easy to capture and display those events only occur once which referred as the transient phenomenon. Therefore, we can deal with the results by using oscilloscope itself or computer for analyzing, archiving, printing or with the other processing. The waveform on the DSO oscilloscopeneedn’t to be continuously, although the signals have disappeared, the waveform still can display. Unlike the analog oscilloscope, DSO can retain the signal durable and extend the methods of waveform processing. However, DSO has not real-time brightness level, they can’t represent the different brightness levels of the actual signals.
Some subsystems which composed of digital storage oscilloscope are similar to analog oscilloscope. However, DSO oscilloscope contains more data processing subsystems, so it can display all the data of entire waveform. From capturing signals to the waveform was displayed on the screen, DSO is using serial processing architecture.
The same with analog oscilloscope, the first part (input) of digital storage oscilloscope is the vertical amplifier. At this stage, it is convenient for you to adjust the range of the location by using vertical amplifier.
Then, at the ADC section of the level system, the signals are sampling in real time at discrete points. The signal voltage of sampling position is transformed into numeric value. So the numeric value is called sampling points. The management process of the department is called digital signal. The sampling clock of the level system decides the frequency of the ADC sampling. This rate is called sampling rate, expressed as sample values per second (S / s).
The ADC sampling points are stored in the area of capture storage, so they are called waveform points. Several sampling points can form a waveform point. Waveform points together form a waveform record. The number of waveform points for creating a waveform record and the record is called the record length. Trigger system decides the start point and the end point of the record.
There is a microprocessor in the digital storage oscilloscope signal channel. The signals to be tested is displaying on the screen before processing by the microprocessor. Microprocessor can process the signal, adjust operation of the display, manage the front panel device, and so on. Signals passed the memory, and displayed on the oscilloscope screen finally.
In the range of the DSO oscilloscope ability, the sampling points after additional processed will enrich the display. At the same time, we can strengthen the function of pre-trigger, so that we can observe the results before the trigger points. At present, most digital oscilloscopes also provide automatic parameter measurements, making the measurement process simple.
Digital storage oscilloscope provides high-performance signal-pulse processing and multi-channel capability. DSO oscilloscope is a perfect tool for high-speed, multi-channel applications which is low repetition rate or pulse. In the practice of the digital design, engineers often check four-channel even more signals at the same time, so DSO has become the standard partner with engineers.

The Basic Composition of Digital Oscilloscope
We know as long as we control the voltage which on X-axis and Y-axis deflection boards on digital oscilloscopes, we can control the graphic shapes on CRT display. An electronic signal is the function of time f(t), which changes with time. Therefore, we can plus a voltage which is proportional with the time variable of the X-axis on CRT, and plus test signals on Y-axis, the graphics which are produced by the measured signals change with time. Among the electronic signals, the signal is proportional with the time variable in a period of time which is called sawtooth wave.
Digital oscilloscope is consisted of CRT, X-axis, Y-axis, Z-axis system and power supply.
Test signal ①was accessed to "Y" input terminal, and appropriate weakened by attenuator of Y-axis, then was sent to the Y1 amplifier (preamp), then push-pull output signal ②, ③. Through delay class to Y2 amplifier will be have a delay timeГ1. After amplifying it generate amplified signal ④, ⑤, added to the Y-axis deflection board on CRT of digital oscilloscope. In order to display the signal stable and completely, we can make the test signal③ access to the trigger circuit of the X-axis system, when we lead into positive or negative of the signal, and produce trigger pulse, then switch on sawtooth wave scanning circuit(time base generator) and produce scanning voltage⑦. As there is a period of time for delayГ2 from trigger to switch on scanning, ensure X-axis have started scanning before the signals of Y-axis are sent to the screen, so the delay timeГ1 which on X-axis should slightly larger than the delay timeГ2 which on X-axis. The scanning voltage⑦ through the amplifier of X-axis and amplified by the amplifier, push-pull output ⑨, ⑩ then adding ⑨, ⑩ to the X-axis deflection board on the CRT. Z-axis system is for amplifying scanning voltage on the way, and changing it to positive rectangular wave, at last send them to the gate of CRT on digital oscilloscope. This makes the waveform has a fixed luminance and wiping traces scan in return.
These are the basic parts of digital oscilloscopes. Dual trace show is using the electronic switch to display the two different signals which are input from Y-axis. As the function for human’s eyes have persistence of vision, when converting high frequency to a certain extent, we will see two stable and clear signal waveforms.
Digital oscilloscopes always have a square-wave generator of accuracy and stability, just for verifying the oscilloscopes.

How The Digital Oscilloscopes Measure Small Signals
People who know about the principles of digital oscilloscopes can know they are sampling with high speed ADC. In order to ensure get high sampling rate, so the ADC number of digital device is only 8 bit, so the noises of themselves is relatively high. Particularly when we testing the small signals, as the noise of small signals is not much higher than the noise of digital oscilloscopes, therefore, the signal noise ratio (SNR) is very bad. For example, a signal which is common in the communication, the frequency of it is low and the amplitude is small, so the noise of the digital oscilloscope above the signal will lead to the signal displayed unclear, therefore it is not easy card by cursor.
To improve the SNR, the common way we think is to use the function of waveform averaging on digital oscilloscopes. Averaging function is through multiple acquisitions, make the number of waveforms superimposed and average the noise, but only for repeatable signals. However, the signal is non-repeatable, make the signal waveforms superimposed then confuse itself, let alone to measure.
There are a lot of non-repeatable small signals need to be measured in practical applications, such as a power pulse, the signals from sensor, the ripple of power supply. As they are non-repeatable signals, so they can not use the function of average to be measured. But how to improve the accuracy of the measurement when measure these signals? The answer is to use the high-resolution mode of the digital oscilloscope.
The high resolution mode, that is to say average adjacent multiple points from a waveform which is collected by digital oscilloscope. We should notice the difference between high-resolution mode and the average mode. Average mode is made the points of the same position which on many waveforms averaged. And high-resolution mode is made the points which are adjacent on the same waveform averaged. Though the essence of high –resolution is average, only one waveform is OK and not need many acquisitions.
By setting the high-resolution mode, we can see the effect of noise which on the digital oscilloscope is eliminated out much, the signals become more clearly, more accurate measurements will be.
However, the high-resolution mode is not omnipotent, the essence of averaging the adjacent sampling points is low pass filter of the signals, so if there are some high frequency components of the signal will be averaged out. From the waveform diagram, when the device is set to the high-resolution mode, the more points, the more clear signals, but the lower the bandwidth of the digital oscilloscope.
From that, we can see high-resolution mode improves the accuracy of measurement is to sacrifice for the bandwidth of digital oscilloscope. Therefore, high-resolution mode is not for the measurement of the high-frequency signals. The measurements for the high-frequency small signals are depending on the noisy indicators of the measuring instruments.

The Automatic Test System of Digital Oscilloscope
With the development of electronic technology, digital oscilloscopes have greatly expanded the work ability by the digital technology and software. When we have used the digital oscilloscopes always had some troubles in the early time, for example: low sampling rate, a big dead time and low refresh rate of the screen. However, these problems have been improved greatly. It was difficult for observing modulation signal, eye diagram communicationsvideo signaland other complex signals in the past. Now, it has changed. They are easy for observed. Digital oscilloscope can operate on the data and analysis, particularly suited for capturing the details and exceptions of complex dynamic signals.
Therefore, digital oscilloscope has been widely used in scientific researches and industrial productions. In order to make the digital oscilloscopes work in the qualified status, it is an urgent task for test engineer to have a regular basis, rapid and comprehensive testing and ensure traceability on digital oscilloscope.
As the manual test is inefficient and error-prone, so each test engineer needs to read a lot of test data for the testing of digital oscilloscopes. Automatic test system can test the parameters quickly, display the test results directly and store the test data automatic. The traditional manual test can not be achieved these characteristics. It is a trend for testing the equipment by automatic test system.
GPIB, VXI, PXI is availablefor automatic test system standard bus line. As the performance of GPIB is stable, easy to operate and low price, so it obtain the acceptance of users. So we choose the GPIB as the bus line for the test system of digital oscilloscopes.
How to Use Digital Oscilloscopes to Measure Special Signals
(part two)
In the last article, I have introduced two ways of special use for digital storage oscilloscope. Now, I will introduce other two ways of measuring special signals.
3. Test the jitters in periodic signal
Some high-end digital storage oscilloscopes have a specialize software which is for testing jitter, so they can use this function go with comprehensive jitter measurements.However, the digital storage oscilloscope which has no jitter software only through the infinite persistence to test signals for cumulative time. In addition, we can use cursors to measure the jitter from peak to peak, so that the measurement results will be more reliable. For example, the following steps to set the measurement for a common one:
(1) Press the “CURSOR” button;
(2) Press the “Function” button in the screen;
(3) Select V Bars cursors;
(4) Press “Bring Both Cursors On Screen” button to quickly locate the screen cursor;
(5) Place a cursor in the edge of the first down, and place another cursor in the edge of the last down.
(6) Read jitter time from the peak to peak
4. Capture real signals by correct using the probe
The people who is design or test in any measurement, always needs the realistic signals by the oscilloscope. Application of the digital oscilloscopes should not affect the signal itself in any way, but almost any test will has an impact on the signal. It is very important by using probe correctly, so the probe can make the signal more realistic. When you connect a probe to any input channel first, it should compensate the probe till the oscilloscope has input. It can come true a best measurement as the probe and input channel have matched. When you use the probes which are random match with the digital oscilloscope should not to set the impedance to 50Ω, because the impedance of probe in parallel with the one of input will cause the impedance of test circuit input less than 50Ω, so test the high resistance of the electrical signal will lead to a false appearance which is can not capture any signals.
In addition, probe in a common digital oscilloscope has a ground wire. With the measured points form a loop antenna similar to the path interference, it will lead to a relatively large interference. The way to reduce the interference is to remove the cap of the probe, and not to use the ground wire which is connected the probe but directly use the tip and internal of the probe to test.

How to Use Digital Oscilloscopes to Measure Special Signals
(part one)
With the rapid development of digital technology and integrated circuits, digital storage oscilloscopes as their powerful testing capabilities, stable performance and more efficient data processing functions are used in much scientific researches and productions, have become the most effective detection of electronic circuits tool. Through viewing the key points of the circuits for voltage and current waveform on the oscilloscope, we can check directly whether circuits are working normal and whether the design is reasonable. It is helpful for improving design and products, not only depend on the advantage of the instruments, but also with the test way and the experience of engineers.
Digital oscilloscope has a high sensitivity as it with a high gain amplifier, so it can easy observe the weak signals. In aviation, aerospace, products testing in electronics, testing, the applications of digital oscilloscopes are increasingly common. Now, digital oscilloscope is no longer limited to measure the pulse parameters of the waveform, it can test the spectrum through transforming the FFT of time / frequency, as well can obtain signal jitter diagram by the clock. Therefore, it is the multi-purpose instrument which is preferred for testers.
1. Capture a random single signal pulse
Some signals appear at boot time, and disappear after start complete. How does digital oscilloscope capture these signals? Some testers may use this way: once the tested signals appeared in the screen, just press the “stop” button. Obviously, the success rate of this method is not high, especially for some high-speed signals. The correct way is to use a single trigger function of digital oscilloscope, so can capture the single-pulse signal automatically. For example, a common digital oscilloscope can be realized the correct measurement by the following steps:
(1) Adjust the scale of the vertical and horizontal to the range which you want to view;
(2) Press the “MENU” button to capture;
(3) Press “ResoluTIon” screen button;
(4) Select Normal acquisition resolution;
(5) Press the “SINGLE SEQ” (single order) button.
“SINGLE SEQ” button can set the trigger parameters of a single pulse correctly.
2. The optimization of capturing signals and getting data
Before we use digital oscilloscope to capture next signals, we can adjust the controls of vertical and horizontal to have a preview about how to display the signals. When adjusting the controllers, the current was reconfigured, expanded or compressed, so the preview is very helpful for having an optimization before capturing the signals.
When we have set a new scale of vertical and horizontal, we can get more signal details. When you read the data and find the data only in the screen, moreoverthe resolution is according to time interval, we can use the function of screen extension to capture more testing details. In addition, new type of digital storage oscilloscopes are used on WINDOWS platform which is completely open, supporting Matlab, LabVIEW, VB, VC and other software. Using these software can deal with data analysis and processing flexible.
More special measuring ways of digital storage oscilloscope will be introduced in the next article. Thank you.

The understanding of professional digital oscilloscope
Oscilloscope is an instrument that can let signal voltage be viewed as a graph on the screen. This device is powerful for displaying and observing electrical signals. They can display a signal as well as distortion and frequency when the time between two events or the relative timing of two cycles.
A device that provides digital illustration of electrical signal is called as digital oscilloscope. However, professional digital oscilloscopeis available in many kinds, among digital storage and USB digital and digital PC oscilloscope. Now, there are many bands and types of oscilloscope in the market, but they generally do the same job. The signal was measured, and forwarded to the input connector. In general, the instrument has more than one input connector. This input connector electronic of the device can measure and analysis various signals. The signal to be measured is introduced into one of the input connectors. As they have several input connectors, so they can capture thousands or millions of data points and stored them until the waveform displayed on the screen.
The analog and digital models can be adapted to general purposes, but have different characteristics that can be adapted for different specific purposes. A digital one can only capture single signal. It can store and display waveform. It is capable of sending information to computers and other devices for the analysis and many others. There are six parts of the digital oscilloscope. They are analog vertical input amplifier, analog-to-digital converter and digital waveform memory, triggering and clock drive, circuits, LCD or LED screen, and power supply.
There are only three classifications of digital oscilloscope. They are digital storage (DSO), digital phosphor and sampling oscilloscope. Each has strength and weakness over the other, therefore these must be considered when looking for your digital one.
There are some useful and popular digital oscilloscopes. They general provide dual channel with a good trigger function. The bandwidths of them always include 25, 40, 60 and 100 MHz with the USB 2.0 standard interface. But also they have cursor measurements from manual to auto measures. Especially with the FFT can more efficiency.

The Choice for Digital Oscilloscopes
Ⅰ.Overview
Digital circuit is developed rapidly in the eighties, whose testing tools - digital oscilloscope. They are springing up like mushrooms. As the price of a digital oscilloscope is more expensive than an analog oscilloscope. So we should choose a digital oscilloscope according to our needs. We shouldn’t go after high–index blind, otherwise will make a great unnecessary waste. The price of a low level oscilloscope is out of line with the high-end quality one. The difference between them is almost 50 times in the price, among (8,000-50 million) RMB.
Ⅱ. How to choose is reasonable
1. Bandwidth
If you want to accurate the relation between the selection bandwidth and the highest frequency of the signal. First, we look at the following example: a 50MHz pulse signal.
From the graph which on different bandwidth oscilloscope, we should choose the bandwidth of the oscilloscope 3-5times as the signal frequency and accurate measurement 8-10 times or more as the signal frequency, as in order to ensure the extension of the test signal amplitude and increase the accuracy.
2. Sampling

Notice the Bandwidth When Using Digital Oscilloscope
Digital oscilloscope has unique features like waveform triggering, storage, display, measurement, waveform data analyzing and processing and so on, whose usage is increasingly popular. As there is a big difference between the performance of digital oscilloscopes and virtual oscilloscopes, if used improperly, it will lead to a large measurement error and affect the test tasks, so we must pay more attention to the bandwidth. First let’s learn the differences of them.
Bandwidth is the most important indicator of the oscilloscope. Virtual oscilloscope has a fixed bandwidth, while that of digital one can be divided into virtual and digital real-time.
For repetitive signals using sequential sampling or random sampling techniques, digital oscilloscopes can achieve a maximum bandwidth that is the real-time one. The highest digital real-time bandwidth and frequency and waveform reconstruction of K-related factors (the bandwidth = high rate / K), are generally not given directly as an indicator. From their definition,we can see that virtual bandwidth is only suitable for repeated measurement of periodic signals, while the other one is suitable for signals and single signal measurement. Manufacturers claim the bandwidth of the oscilloscope can reach how much megabyte. However, they refer to analog bandwidth. Digital real-time one is less.
Therefore, when you choosing a digital oscilloscope, you should not believe the description about the bandwidth by manufactures as they mean to the analog bandwidth. Especially, when measure a single signal, we must refer to the bandwidth of the oscilloscopes, or unexpected errors will occur during measurement.
youroscilloscope.com offers all kinds of digital oscilloscopes for you to wholesale. Other practical oscilloscopes are provided with cheap price as well.

How to Choose a Correct Oscilloscope(part two)
In the last article, I have listed three factors about how to choose a correct oscilloscope and I will go with another five factors which would help you get an oscilloscope as much the performance under the budget.
.4. Trigger
When you choosing an oscilloscope must consider trigger, make sure the oscilloscope can support the trigger function of the basic edge and video. So that the oscilloscopes can find specific signal activities quickly.
5. The features of measurement and analysis
Automatic measurement such as period, frequency, average peak, which is very helpful for signal test and fault detection. More advanced analysis capabilities are needed, such as signal averaging and FFT. Signal averaging can eliminate the extra noise which display on the oscilloscope waveform, so that you can only check useful signal characteristics.
6. Dimensions
As area of the table is limited, so we will concern about the size of the oscilloscope. Engineers like smaller scope, because it easy to carry. However, the smaller scope doesn’t mean the better performance .When choosing an oscilloscope we should not give up the performance or number of channels as the size.
7. Ease of use
If engineers master the performance of the oscilloscope faster, so they will go on a meaningful measurement easier. As engineers often use this tool, so the user interface of oscilloscope should be more friendly, the engineers can get higher efficiency.
8. Communication
---- Digital Storage Oscilloscope (DSO) supports the communication interface of RS-232 and GPIB .It is good for engineers to make remote measurements or automate the measurement sequence. Another major advantage of DSO is can support a hard copy with a single key.

How to Choose a Correct Oscilloscope(part one)
A few years ago, the analog oscilloscope was the only candidate among desktop products. Today, cheap digital storage oscilloscope (DSO) has came into the market, providing more choices for engineers to choose.
DSO has unique features like waveform triggering, storage, display, measurement, waveform data analyzing and processing and so on, whose usage is increasingly popular. But not all the DSO is the same. Many digital storage oscilloscopes only have two complete channels for signal acquisition complete, the user can’t do anything with it when they want to watch multiple test points on the circuit.
In this case, how to choose a correct oscilloscope becomes a challenging problem. Here we list eight factors that engineers need to consider according to the importance, so that engineers can make the right choice when choosing.
1. Bandwidth
Oscilloscope should have enough bandwidth to capture and display the fast signals in application both in current and future. A common experience is the bandwidth of oscilloscope is measured at least three times as the highest signal frequency.
2. Price
Every engineer needs a desktop oscilloscope, which means you may need to buy several or hundreds of oscilloscopes according to the scale of your company. It is a major investment to get each engineer an oscilloscope. Many companies use the $ 2,500 or more money to buy an oscilloscope reluctantly, unless the equipment can be shared by a team of engineers. However, if each engineer must have an oscilloscope, how to make the least spend is the most concerned question.
3. performance
When the design is required to be finished as soon as possible, users may expect higher performance of the oscilloscope. When using high-speed processors, engineers must be able to detect anything that would harm the system and reduce the events of sporadic and transient. It requires the oscilloscope to support high-speed capture of transient events, advanced measurement and analysis capabilities like fast Fourier transform (FFT).
Higher performance means higher price, so to get the highest performance at the most extent within the funding budget is the main goal .The oscilloscope which is Selected should have four complete channels and the highest sample rate. Closing to 1G samples / sec sampling rate can ensure the instrument to capture and display high-speed events, such as burrs or jitter. Users must confirm the marked sampling rate is the same for all channels. In order to get a higher sampling rate ,many cheap DSO to overlap in a channel sampling on the head. If all channels are working, each channel can only get part of the sampling rate.
DSO should also support real-time acquisition, enabling the oscilloscope to capture non-repetition of the signal characteristics. It is very important when tracking the pulse distortion and the occasional transient signal when is abnormal, This performance is very important.
In the next article, I will go with the else factors which should notice when choosing a correct oscilloscope.
A few years ago, the analog oscilloscope was the only candidate among desktop products. Today, cheap digital storage oscilloscope (DSO) has came into the market, providing more choices for engineers to choose.
DSO has unique features like waveform triggering, storage, display, measurement, waveform data analyzing and processing and so on, whose usage is increasingly popular. But not all the DSO is the same. Many digital storage oscilloscopes only have two complete channels for signal acquisition complete, the user can’t do anything with it when they want to watch multiple test points on the circuit.
In this case, how to choose a correct oscilloscope becomes a challenging problem. Here we list eight factors that engineers need to consider according to the importance, so that engineers can make the right choice when choosing.
1. Bandwidth
Oscilloscope should have enough bandwidth to capture and display the fast signals in application both in current and future. A common experience is the bandwidth of oscilloscope is measured at least three times as the highest signal frequency.
2. Price
Every engineer needs a desktop oscilloscope, which means you may need to buy several or hundreds of oscilloscopes according to the scale of your company. It is a major investment to get each engineer an oscilloscope. Many companies use the $ 2,500 or more money to buy an oscilloscope reluctantly, unless the equipment can be shared by a team of engineers. However, if each engineer must have an oscilloscope, how to make the least spend is the most concerned question.
3. performance
When the design is required to be finished as soon as possible, users may expect higher performance of the oscilloscope. When using high-speed processors, engineers must be able to detect anything that would harm the system and reduce the events of sporadic and transient. It requires the oscilloscope to support high-speed capture of transient events, advanced measurement and analysis capabilities like fast Fourier transform (FFT).
Higher performance means higher price, so to get the highest performance at the most extent within the funding budget is the main goal .The oscilloscope which is Selected should have four complete channels and the highest sample rate. Closing to 1G samples / sec sampling rate can ensure the instrument to capture and display high-speed events, such as burrs or jitter. Users must confirm the marked sampling rate is the same for all channels. In order to get a higher sampling rate ,many cheap DSO to overlap in a channel sampling on the head. If all channels are working, each channel can only get part of the sampling rate.
DSO should also support real-time acquisition, enabling the oscilloscope to capture non-repetition of the signal characteristics. It is very important when tracking the pulse distortion and the occasional transient signal when is abnormal, This performance is very important.

Although the terminology for the different classes of generators is not standardized, there is a general market consensus that all the generators fall into three category, namely signal, function and waveform generators.
The most commonly used one is AWG.
AWG, which is short for Arbitrary Waveform Generator, is a kind of signal source. It has all the characteristics of the signal sources and it can generate waveforms of any design. In this case, arbitrary waveform generators can meet all sorts of simulation and testing requirements, which makes design and debugging very convenient.
The constructed waveform is converted to an analog signal using a digital-to-analog converter (DAC) operating at clock rates up to a few GHz. The varieties of waveforms that may be generated with an AWG include standard functions (sine, square, pulse, triangle, ramp), non-standard functions (sin(x)/x, exponential, cardiac, noise, etc.) compliance test waveforms (video color bar pattern, AM/FM radio tones, encoded communication test signals, etc.), a combination of signals (multi-tone, noisy sine wave, or digital pulse stream with transient spikes, etc.), or the playback of signals captured with digital oscilloscopes. AWG usually works with PC via the USB cords.
Unlike function generators, arbitrary waveform generators can generate any arbitrarily defined waveform as their output, any point-by-point synthesis. The application covers capture-playback, custom signal and compliance test. AWG is often used as a modulation source that is applied to the RF signal generator, which allows the highly flexible AWG to generate a complicated or lengthy modulation signal for the signal generator’s high-frequency sine wave output. Two-channel arbitrary waveform generators will provide complex I/Q vector modulation. Some of them can even work as conventional function generators by using on-instrument algorithms to generate standard functions.
Recently, Beijing Rigol Technologiesfirstly launch a new generation of domestic direct digital frequency synthesis (DDS) signal generator DG3000 series. They are able to generate high accuracy and high stability sine waves, square waves, and other popular waveforms. They can also generate programmable pulse signals. With powerful functions and user-friendly design, it offers a good choice for Arbitrary Waveform Generatorfans.
Other than the functional waveforms, the arbitrary waveform feature allows engineers to generate any desired waveforms through the use of Ultra Wave, the application and waveform editing software. Surely theywill become very popular in the market.

Avoid Aliasing Phenomenon When Using Digital Oscilloscope
Digital sampling rate, also called speed, is the frequency of analog input for signal sampling in the unit of time. It always shows as MS / s. Sampling rate is as an important indicator ofdigital oscilloscope.
Let’s see how it works:
1. If the sampling rate is not high enough, it will prone to aliasing phenomenon If the input signal of oscilloscope is a 100KHz sine signal, but the oscilloscope shows the signal frequency is 50KHz .What happened? This is because the sample rate of oscilloscope is too slow, leading to the aliasing phenomenon. Aliasing is a phenomenon that frequency of the waveform showed on the screen less than the actual frequency of the signal, or even if the lights of trigger on the oscilloscope has on, but waveform is still not stable. So for an unknown frequency waveform, how to determine whether it hasran into aliasing .We can change scan rate by t / div to a faster time base file, to see the frequency of the waveform parameters whetherit has drastically changed. If so, the wave-aliasing has occurred. Another situation is, theshaking waveform was stabilized in a faster time base file, which also shows the waveform aliasing has occurred. There are several ways to prevent aliasing occur easily:
• Adjust the scan rate;
• Automatic set-up;
• Try to switch to the collection method or in peak envelope detection method .As the envelope approach is to look for extreme from many collection of records, and the peak detection method is to look for minimum and maximum from the single record. So the two methods can detect the changes of fast signal;
• If there has an Insta Vu mode on oscilloscopes, you can choose it , because it can get waveform fast .The waveform shown in this way is similar to which showed by an analog oscilloscope.
2. The relationship between Sampling rate and t / div
Maximum sampling rate on every digital oscilloscope is a fixed value. However, a scan at any time t / div, the sampling rate fs is given by:
fs = N / (t / div) N is a sample point for each grid
In a word , when using digital oscilloscopes, in order to avoid aliasing, you’ d better put the scan rate to faster file. If you want to get the fleeting glitch, you’d better put the scan rate to slower file.
