Page 10: Introduction To The Scpi Language
1 34450A Remote Operation Introduction to the SCPI Language SCPI (Standard Commands for Programmable Instruments) is an ASCII-based instrument command language designed for test and measurement instruments. 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 .
Page 11 1 34450A Remote Operation Command Separators A colon ( : ) is used to separate a command keyword from a lower-level keyword. You must insert a blank space to separate a parameter from a command keyword. If a command requires more than one parameter, you must separate adjacent parameters using a comma as shown below: CONF:VOLT:DC 10,3.0E-05...
Page 12: Scpi Parameter Types
1 34450A Remote Operation IEEE-488.2 Common Commands The IEEE-488.2 standard defines a set of common commands that perform functions such as reset, self- test, and status operations. Common commands always begin with an asterisk ( * ), are three characters in length, and may include one or more parameters.
Page 13 1 34450A Remote Operation ASCII String Parameters ASCII string parameters can contain virtually any set of ASCII characters. A quoted ASCII string parameter must begin and end with matching quotes; either with a single quote or a double quote. You can include the quote delimiter as part of the string by typing it twice without any characters in between.
Page 14: Keysight 34450A Command Quick Reference
1 34450A Remote Operation Keysight 34450A Command Quick Reference Syntax Conventions — Braces ( { } ) enclose the parameter choices for a given command string. The braces are not sent with the command string. — A vertical bar ( | ) separates multiple parameter choices for a given command string. The bar is not sent with the command string.
