IEEE 488.2 Common Commands

 

Description 

ANSI/IEEE Standard 488.2 defines the codes, formats, protocols, and usage of 

common commands and queries used on the interface between the controller and 

the instruments. The instrument complies with this standard. 

 

 

Command and Query

 

Structure

 

The syntax for an IEEE 488.2 common command is an asterisk (*) followed by a 

command and, optionally, a space and parameter value. The syntax for an IEEE 

488.2 common query is an asterisk (*) followed by a query and a question mark. 

All of the common commands and queries are listed in the last part of the 

Syntax 

and Commands 

section. The following are examples of common commands: 

*CLS 

The following are examples of common queries 

*IDN?
