Edge trigger, edge trigger, trigger level can be set, rising edge or falling edge.Edge trigger is also called basic trigger.
advanced trigger, which contains all kinds of different trigger functions. According to the characteristics of the measured signal, the corresponding trigger conditions can be set to locate the waveform of interest. Advanced trigger is the key of circuit debugging.During circuit debugging, if you don't know the possible problems of the tested signal in advance, you can shorten your debugging cycle by using different advanced trigger functions to locate the details of the fault.
For example: when we look at the lower frequency waveforms, we see a small area that is black.
