How to measure the time difference between two signals

　　In the actual waveform measurement process, how do you measure the time difference between two channel signals?

　　Manual cursor measurement? This is indeed a common method, but it will inevitably cause some measurement errors. Is there any better way? Let's first look at how the ZDS2022 oscilloscope measures the time difference between two signals.

　　The 51 parameter measurement statistics of the ZDS2022 oscilloscope include voltage, time, count and some other commonly used measurement parameters. In fact, the delay in the time category is the time difference between the two channel waveforms. Rotate knob B to select the delay between the rising edge and the rising edge. Long press knob B, and the ZDS2022 smart dictionary window will explain the parameter with pictures and texts. Select the corresponding delay type according to your actual needs and return to the main interface. The time difference result of the two channel waveforms will be automatically measured, completely avoiding the error caused by manual measurement. It is not only easy to operate, but also practical!
