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 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".
Digital output
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".
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.
Turn On/Off Voltage Monitoring Output Terminal
The terminal outputs the 0-to-+10 V voltage signal, which indicates the zero-to-full
scale real-time input voltage.
In the system setting tab, press the Up/Down arrow key to switch the parameter
focus to "Vmon_EXT", and then press the Left/Right arrow key or use the knob to
enable or disable the voltage monitoring function.
