4.3 SCPI PROGRAMMING
SCPI (Standard Commands for Programmable Instruments) is a programming language con-
forming to the protocols and standards established by IEEE 488.2 (reference document ANSI/
IEEE Std 488.2, IEEE Standard Codes, Formats, Protocols, and Common Commands). SCPI com-
mands are sent to the Interface Card as output strings within the selected programming lan-
guage (PASCAL, BASIC, etc.) in accordance with the manufacturer’s requirements for the
particular GPIB interface card used.
