the input signal, that is, trigger on the rising and falling edges of the input
signal.
Entering the edge trigging, the trigger setting information is displayed at the
bottom right corner of the screen, e.g.
trigger type is rising edge, the trigger source is CH1, the trigger coupling is DC,
and the trigger electrical level is -20.0mV.
The description of the trigger system setting menu is as follows:

Trigger electrical level: The amplitude level that the signal must cross when
setting the waveform acquisition. Press the Trig/△ key to enter the trigger

Set Channel 1 as the source trigger signal.
Set Channel 2 as the source trigger signal.

Set to allow all components to pass through.
Waveforms can be acquired without detecting
trigger conditions.
The waveform is acquired only when the trigger
conditions are met.
When a trigger is detected, a waveform is sampled
and then stopped.
