The '''Standard Commands for Programmable Instrumentation (SCPI)''' defines a standard set of commands to control programmable [[test and measurement]] devices in [[instrumentation]] systems.

The SCPI Standard specifies a [[command structure]] and [[syntax]] for programmable instruments control. The physical communications link, such as [[GPIB]], [[RS232]], [[USB]], [[VXIbus]] etc, is NOT defined by SCPI. SCPI also includes standard command sets for several classes of instruments, e.g. power supplies, and measurement devices such as voltage measurmentmeasurement and Digitizers (such as [[oscilloscope]]).

SCPI commands are written in ASCII format. Hence, SCPI commands can be sent easily using any programming language including C, C++, Visual Basic, etc. In addition, SCPI is supported by Test Application Software such as Lab View and HP VEE.
