How to use ZDS2022 to realize waveform comparison and analysis in different time periods?

In some cases, it is necessary to compare and analyze waveforms in different time periods. The traditional method is to manually draw the waveforms on paper and then compare them. This is not only inaccurate but also inconvenient. Using the waveform reference function of ZDS2022, you can quickly and easily compare waveforms in different time periods on the same screen. The ZDS2022 oscilloscope can support 3 reference waveform channels at the same time. Press the [Ref] button to open the reference waveform setting menu, select the corresponding signal channel, and then [Save waveform temporarily], as shown in Figure 1.6.
