Chapter 3 Remote Control

The T3PS3000 supports communication with remote computers through USB

and LAN interfaces on the rear panel.

SCPI (Standard Commands for Programmable Instruments) is an ASCII based

programming  language  that  can  be  used  to  control  the  power  supply  from  a

remote computer installed with NI Measurement & Automation software.

In this chapter, we introduce the SCPI commands supported by the T3PS3000.
