Syntax

This section provides an overview of the commands for the IntelliFrame

Mainframe and includes the following topics:

HA brief introduction to SCPI

HA description of the command syntax

HInstructions on how to enter commands

The commands for the mainframe are compatible with IEEE-488.1, IEEE-488.2, and SCPI-1995.0 standards.

SCPI

SCPI (Standard Commands for Programmable Instruments) is a standard created by an international consortium of the major manufacturers of test and measurement equipment. SCPI uses IEEE-488.2 syntax to provide common commands for the same functions of various programmable instruments.

The standard simplifies the task of programming a group of instruments that use SCPI. Instead of having to learn different commands for every instrument, the programmer may use the same commands for the same functions of each instrument.

The controller sends instructions to the instrument in the form of commands or queries. Commands modify control settings or tell the instrument to perform a specific action. Queries cause the instrument to send data or status information back to the controller. A question mark at the end of a command header identifies it as a query.

Command Syntax

Any instruction that you send to an instrument that complies with SCPI must have at least three basic elements:

HCommand header

HParameter (if required)

HMessage terminator or separator
