Standard Commands for Programmable Instruments : ウィキペディア英語版 | Standard Commands for Programmable Instruments The Standard Commands for Programmable Instruments (SCPI; often pronounced "skippy") defines a standard for syntax and commands to use in controlling programmable test and measurement devices. == Overview ==
In 1990, SCPI became defined with the specification.〔(ni.com - History of GPIB - Developer Zone )〕 The standard specifies a common syntax, command structure, and data formats, to be used with all instruments. It introduced generic commands (such as CONFigure and MEASure ) that could be used with any instrument. These commands are grouped into subsystems. SCPI also defines several classes of instruments. For example, any controllable power supply would implement the same DCPSUPPLY base functionality class. Instrument classes specify which subsystems they implement, as well as any instrument-specific features. The physical communications link is not defined by SCPI. While originally created for IEEE-488 (GPIB), it can also be used with RS-232, Ethernet, USB, VXIbus, HiSLIP, etc. SCPI commands are ASCII textual strings, which are sent to the instrument over the physical layer (e.g., IEEE-488). Commands are a series of one or more keywords, many of which take parameters. In the specification, keywords are written CONFigure : The entire keyword can be used, or it can be abbreviated to just the uppercase portion. Responses to query commands are typically ASCII strings. However, for bulk data, binary formats can be used.
