Set Digital Input/Output
A digital I/O interface on the rear panel of the load, supporting digital trigger input
and trigger output.

Digital input
The digital input is the Edge trigger, supporting triggering on the rising or falling
edge.The data line of the Digital I/O interface can receive the external trigger
signal. Once the pre-set trigger conditions are met, the input channel is turned
on or off (ON/OFF), enabling or disabling the trigger function (TRAN). To avoid
misoperation, if you do not need this function, select "Disable" to disable the
function.
In the system setting tab, press the Up/Down arrow key to switch the parameter
focus to "Digital In", and then press the Left/Right arrow key or use the knob to
set it to be "ON/OFF", "TRAN", or "Disable".
Note:

The TRAN function as the digital input is only valid in the following modes:
Con, Pul, Tog, and List.

The interval between the changes of two voltages for the digital input
should be greater than 200 ms.

Digital output
The digital output is a level signal, and the signal can be used for Edge trigger.
When the input channel is turned on or off (ON/OFF), and the trigger function is
enabled or disabled (TRAN), the data line of the digital I/O interface outputs the
level. To avoid misoperation, if you do not need this function, select "Disable" to
disable the function.
In the system setting tab, press the Up/Down arrow key to switch the parameter
focus to "Digital Out", and then press the Left/Right arrow key or use the knob
to set it to be "ON/OFF", "TRAN", or "Disable".
Note:

The TRAN function as the digital output is only valid in the following modes:
Con, Pul, Tog, and List.

Setting the digital output to be "Disable", if the OCP/OPP test is successful,
the digital output is 0; if the OCP/OPP test fails, the digital output of 1.
Enable/Disable the Sense Function
When the DUT outputs large current, after you enable the Sense function, the sense
terminal can be used to accurately measure the voltage across the output terminals
of the DUT to compensate for the voltage drop on the load.
