select the trigger source in the input signal of the input unit.
Trigger slope
The slope refers to the change of the signal from low level to high level
(rising edge) or from high level to low level (falling edge). The slope used as
a trigger condition is referred to as the trigger slope.
Trigger level
The trigger level refers to the level which the trigger slope passes through.
If the signal of the trigger source passes through the set trigger level
according to the specified trigger slope, triggering occurs. When the soft key
