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.

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.

In the system setting tab, press the Up/Down arrow key to switch the parameter

focus to "Sense", and then press the Left/Right arrow key or use the knob to enable

or disable the Sense function.
