Notes on using the ZDS2022 oscilloscope parameter measurement function

The ZDS2022 oscilloscope has up to 51 parameter measurement and statistics functions. Let's learn about the use of parameter measurement statistics by measuring the time parameters of a signal and see how it is different from previous oscilloscopes.

1. Input a square wave signal to the oscilloscope, and use "AutoSetup" to trigger the signal to make it display stably. In order to measure some parameter information of the signal, I decided to try the parameter measurement function of this oscilloscope.

2. Press the "Measure" button to pop up the measurement statistics configuration interface.

3. Select "Parameter Options" to pop up the measurement items. It's a full screen. I counted them and found that there are indeed 51 measurement parameters. When using, you can customize and add specific measurement items as needed.

But what if there are so many parameters and you don’t know the meaning of some of them? In fact, there is no need to worry. After consulting the R&D engineer, it turns out that you can position the B knob to the corresponding item, and long press the B button to pop up the help menu, which contains detailed graphic and text introductions.

In addition, it is not difficult to find that these 51 parameters are divided into three groups: "comprehensive measurement", "time measurement" and "voltage measurement", and the most common measurement items are summarized by group. We can quickly select the measurement group we are most concerned about as needed and quickly measure all the data of interest.

4. After the measurement items are added quickly, press "Return". The measured data is now displayed quickly, and all the measurement items just added are included. In addition, the current value, maximum value, minimum value, average value, standard deviation, and the number of samples currently measured are all displayed. Adjust the offset position of the waveform and find that the knob response is still very sensitive. It is worthy of the use of hardware acceleration, and the effect is very obvious.

5. At this time, if you press the "Clear" button, all measurement statistics can be restarted. There is no such function in other oscilloscopes. In addition, if you want to take a screenshot of the measurement interface and write a report, just plug in the USB drive and gently press the "PrintScreen" button.

The ZDS2022 oscilloscope has many parameter measurement items, simple operation and fast response. In addition, the real parameter measurement statistics function can also help find abnormalities in the signal. The above screenshot reveals that the positive pulse width of the measured waveform is abnormal.
