An Introduction to the SCPI Language

SCPI (Standard Commands for Programmable Instruments) is an ASCII-based
instrument command language designed for test and measurement instruments.
Refer to
introduction to the basic techniques used to program the function generator 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 is the root keyword of the command, FREQuency and SWEep are
second-level keywords, and STARt and STOP are third-level keywords. A colon ( : )
separates a command keyword from a lower-level keyword.
