SCPI Command Syntax
Command hierarchy
SCPI is an ASCII-based command language developed for testing and measuring
instruments. The command structure is organized based on common roots or nodes, which
are the component blocks of the SCPI subsystem. Each command is a combination of
program headers, parameters and punctuation.
The hierarchy is explained using the SENSe subsystem as an example.
• Upper and lower nodes are delimited by a colon (:).
• When a colon is provided at the beginning of the program header, the first node is the
root node.

Format
In this manual, SCPI commands are indicated in the following format.
Example:
MEASure[:SCALar]:CURRent:AC?
• SCPI commands have two forms: the long form that spells out all characters of a
command and the short form that omits characters written in lower-case letters.
SCPI commands can be sent in either the long form or short form.
