4.12 Trigger
The trigger can be used as a trigger source to output high and low level signals to the external instrument, or as a
source under control to trigger the on and off of the instrument output through the external input level.
When triggered by an external signal, the trigger operates in trigger input mode. When the digital I/O interface
detects the trigger signal, the power supply controls the channel action. When the external instrument is triggered,
the digital I/O interface outputs high or low level signals when the trigger conditions are met.
The digital I/O interface on the rear panel needs to be connected, and the high level of IO input should not be
higher than 3.3V to avoid damage to the instrument.
Note: When the trigger operates in trigger input mode, D0~D3 is high level by default, and low level signal needs
to be connected to trigger.
