SCPI (Standard Commands for Programmable Instruments) is a standard that defines a language for communicating with instruments based on messages. The majority of the GPIB instruments use the SCPI but also RS-232, Ethernet, VXI, PXI may use it. Several measurement instrument manufacturers have adopted this standard as HP / Agilent for example, allowing some communication uniformity between several devices. Some examples of SCPI commands: Instrument identification querry: *IDN? Instrument reset: RST Measure querry: MES?
