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?PXI, for PCI eXtensions for Instrumentation, is a bus designed for instrumentation, test and measurement. It derives from the Compact PCI bus, with which it remains compatible, while adding some signals such as clocks and triggers to synchronize multiple cards.
It is used in 3U card size (10 cm) high chassis, 8 to 18-slot card.
