Trigger (option)
The rear panel of DP800 provides a digital I/O interface (as shown below) which
supports trigger input and trigger output.
Trigger Input:
The data lines of the digital I/O interface receive external trigger signal. The
source under control (namely the output channel) turns on the output, turns off
the output or inverts the output state when the preset trigger condition is met.
Trigger Output:
The data lines of the digital I/O interface output level or square signal when the
output of the control source (namely the output channel) meets the preset
trigger condition.
The 4 data lines are mutually independent and can be used as trigger input line or
trigger output line separately.
Press Trigger to open the trigger setting interface as shown in the figure
below. Press Trig to select “In” or “Out” to switch between the trigger input and
trigger output setting interfaces and the default is trigger input.
