Sense protection request on NGx series PSU during remote control

Question

Is there a way to check for sense protection being triggered on my NGx power supply when remote controlling the device?

Answer

You can use the request string

"SOURce:VOLTage:PROTection:TRIPped?"

For example

"INSTrument:NSELect 2

SOURce:VOLTage:PROTection:TRIPped?"

requests the state of channel 2 after preselection

while

"SOURce:VOLTage:PROTection:TRIPped? (@1)"

requests the state of channel 1. This command's extension "(@x)"may not work on some devices depending on the FW version.
