Remote Commands

 

 

The instrument supports some SCPI commands and some instrument specific commands. These 
commands enable a computer to remotely communicate and control the power supply over any 
of the supported remote interfaces:  USBTMC, RS-232, GPIB(non-B MODELS ONLY), RS-485, and 
Ethernet (Model 9117 only).
