Introduction to SCPI
SCPI (Standard Commands for Programmable Instruments) is a programming
language for controlling instrument functions over the GPIB. 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 ac source
display and the display of a SCPI-compatible multimeter.
Conventions used in this guide
Angle brackets < > Items within angle brackets are parameter
abbreviations. For example, <NR1> indicates a specific
form of numerical data.
Vertical bar | Vertical bars separate alternative parameters. For
example, NORM | TEXT indicates that either “TEXT” or
“NORM” can be used as a parameter.
Square Brackets [ ] Items within square brackets are optional. The
representation [SOURce:]LIST 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 parameter “A” must
be entered, while parameter “B” may be omitted or may
be entered one or more times.
Computer font Computer font is used to show program lines in text.
TRIGger:DELay .5 shows a program line.
