GPIB Capabilities Of The Power Supply

All power supply functions except for setting the GPIB address are programmable over the IEEE 488 bus (also known as the General Purpose Interface Bus or "GPIB"). The IEEE 488.1 capabilities of the power supply are listed in the Supplemental Characteristics of the Operating Guide. The power supply operates from a GPIB address that is set from the front panel (see System Considerations at the end of this chapter).

Introduction To SCPI

lmportant Learn the basics of power supply operation (see "Chapter 5 - Front Panel Operation" in the power supply Operating Guide) before using SCPI.

SCPI (Standard Commands for Programmable Instruments) is a programming language for controlling instrument functions over the GPIB (IEEE 488) instrument bus. SCPI is intended to function with standard GPIB hardware and conforms to the IEEE Standard Digital Interface for Programmable Instrumentation. SCPI is layered on top of the hardware portion of IEEE 488.2. The same SCPI commands and parameters control the same functions in different classes of instruments. For example, you would use the same DISPlay command to control the power supply display state and the display state of a SCPI-compatible multimeter.

Note

HPSL and TMSL (Test and Measurement System Language) were earlier versions of SCPI. If you have

 

programmed in either, then you probably can go directly to "Chapter 3 - Language Dictionary".

Conventions

The following conventions are used throughout this chapter:

Angle brackets

< >

Items within angle brackets are parameter abbreviations. For example,

 

 

 

<NR1> indicates a specific form of numerical data.

Vertical bar

 

Vertical bars separate one of two or more alternative parameters. For

 

 

 

example, 0OFF indicates that you may enter either "0" or "OFF" for the

 

 

 

required parameter.

Square

[

]

Items within square brackets are optional. The representation

Brackets

 

 

[SOURce]:CURRent means that SOURce may be omitted.

Braces

{

}

Braces indicate parameters that may be repeated zero or more times. It is

 

 

 

used especially for showing arrays. The notation<A>{<,B>} shows that

 

 

 

"A" is a required parameter, while "B" may be omitted or may be entered

 

 

 

one or more times.

Boldface font

 

 

Boldface font is used to emphasize syntax in command definitions.

 

 

 

TRIGger:DELay <NRf> shows a command syntax.

Computer font

 

 

Computer font is used to show program text within normal text.

 

 

 

TRIGger:DELay .5 represents program text.
