The header and the parameters are separated by a In this article, we will discuss the basics of a SCPI command and, common commands, syntax conventions, and how SCPI commands are used in instrument control. Command Tree SCPI commands are based on a hierarchical structure, allowing the same instrument-control header (or keyword) to be used many times for different purposes [99, Vol. Example of Common command and SCPI commands together The SCPI Commands Sample Guides are offered as visual references with examples of some common/typical commands structures, syntax, but not meant to provide a complete list of all available commands. SCPI (Standard Commands for Programmable Instruments) SCPI commands - messages - are used for remote control. Note that SCPI commands typically build up parameter types that accept more than one 488. They operate the Common Commands and SCPI Commands. The corresponding command syntax would be: When sending a message containing the previous command, you would actually type: SOUR:POW ON. The SCPI Standard is built on the foundation of IEEE-488. They can contain measurement results, instrument settings and A SCPI Command Structure. Parameters. The braces are not sent with the command string. 134. A typical command is made up of keywords prefixed with colons (:). Once familiar with the organization and structure of SCPI, considerable efficiency gains can be achieved during control program development, independent of the control program language selected. S ee Also. The first layer of commands is composed of general commands. They have a hierarchical structure with a «root» level and one or more sub-levels known as «nodes». 13.

In chapter 6, all remote control functions are described in detail. There are different types of instrument messages: • Commands • Instrument responses Commands Commands (program messages) are messages which the controller sends to the instrument. So just how is the SCPI command structure oriented? SCPI commands are ordered in a hierarchical structure and related commands are then grouped into subsystems. Braces ({}) enclose parameters within a command string. 2.
