Standard Commands for Programmable Instruments (Programmable Instruments)
Standard Command set. SCPI is a standard instrument programming language based on
the existing standards IEEE488.1 and IEEE 488.2, and follows the floating-point
arithmetic rules of IEEE754 standard, ISO646 information exchange 7-bit coding symbol
(equivalent to ASCll programming) and other standards. It adopts a set of commands with
hierarchical structure in tree structure, puts forward a universal instrument model, and
adopts signal-oriented measurement. Its mnemonic generation rules are simple, clear and
