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.
. It indicates that the
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:

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

Set to prevent DC component from passing
through.
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.

Trigger on the rising edge of the signal.
Trigger on the falling edge of the signal.
Trigger

Forced trigger key, which forcibly generates a
trigger signal, mainly used in the "normal" and
"single" modes of the trigger mode.
