Introduction to the SCPI Language
Standard Commands for Programmable Instruments (SCPI) is an ASCII- based instrument command language
designed for test and measurement instruments. Refer to Simplified Programming Overview for basic techniques for
programming the power supply over the remote interface.
SCPI commands are based on a hierarchical structure, also known as a tree system. In this system, associated
commands are grouped together under a common node or root, thus forming subsystems. A portion of the SOURce
subsystem is shown below to illustrate the tree system.
[SOURce:]
CURRent {<current>|MIN|MAX|UP|DOWN} CURRent? [MIN|MAX]
CURRent:
TRIGgered {<current>|MIN|MAX} TRIGgered? {MIN|MAX}
VOLTage {<voltage>|MIN|MAX|UP|DOWN} VOLTage? [MIN|MAX]
VOLTage:
TRIGgered {<voltage>|MIN|MAX} TRIGgered? {MIN|MAX}
SOURce is the root keyword of the command, CURRent and VOLTage are second-level keywords, and TRIGgered is
the third- level keyword. A colon (:) separates a command keyword from a lower- level keyword.
