28 Programming Fundamentals

SCPI Language Basics

This section is not intended to teach you everything about the SCPI (Standard Commands

for Programmable Instruments) programming language. The SCPI Consortium or IEEE can

provide that level of detailed information.

Topics covered in this chapter include:

• “Command Keywords and Syntax" on page 582.

• “Creating Valid Commands" on page 582.

• “Special Characters in Commands" on page 583.

• “Parameters in Commands" on page 584.

• “Putting Multiple Commands on the Same Line" on page 586.

For more information refer to:

IEEE Standard 488.1-1987, IEEE Standard Digital Interface for Programmable

Instrumentation. New York, NY, 1998.

IEEE Standard 488.2-1987, IEEE Standard Codes, Formats, Protocols and Comment

Commands for Use with ANSI/IEEE Std488.1-1987. New York, NY, 1998.

Command Keywords and Syntax

A typical command is made up of keywords set off by colons. The keywords are followed by

parameters that can be followed by optional units.

Example: SENSe:FREQuency:STARt 1.5 MHZ

The instrument does not distinguish between upper and lower case letters. In the

documentation, upper case letters indicate the short form of the keyword. The lower case

letters, indicate the long form of the keyword. Either form may be used in the command.

Example: Sens:Freq:Star 1.5 mhz

is the same as SENSE:FREQ:start 1.5 MHz

The command SENS:FREQU:STAR is not valid because FREQU is neither the short, nor

the long form of the command. Only the short and long forms of the keywords are allowed in

valid commands.

Creating Valid Commands

Commands are not case sensitive and there are often many different ways of writing a

particular command. These are examples of valid commands for a given command syntax:

1 2 ... 577 578 579 580 581 582 583 584 585 586 587 ... 621 622
