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 [[IEEE-488 | GPIB (IEEE-488) ]], [[RS232]], [[USB]], [[VXIbus]] etc, is NOT defined by SCPI. SCPI also includes standard command sets for several classes of instruments, e.g. power supplies, loads, and measurement devices such as Voltmetersvoltmeters and [[oscilloscopes]]. A predecessor of SCPI, but with more limited scope, was [[IEEE-488 |IEEE 488.2]] in 1987.

SCPI commands are [[ASCII]] textual strings, which are sent to the instrument over the physical layer, such as GPIB.
