PCI eXtensions for Instrumentation (PXI) is a modular instrumentation platform originally introduced in 1997 by National Instruments.PXI is promoted by the 69-member PXI Systems Alliance (PXISA), whose sponsor members are (in alphabetical order) ADLINK, Cobham Wireless, Keysight Technologies, Marvin Test Solutions, National Instruments, Pickering Interfaces and Teradyne.
CPU cards include Peripheral Component Interconnect (PCI) cards, modular PC Cards, Industry Standard Architecture (ISA) cards, PCI extensions for instrumentation cards and embedded technology extended (ETX) cards. CPU cards are often used to expand the memory, speed, bandwidth or embedded applications of an existing computer system.
PCI eXtensions for Instrumentation, , is a peripheral bus specialized for data acquisition and real-time control systems. Introduced in 1997, PXI uses the CompactPCI 3U and 6U form factors and adds trigger lines, a local bus, and other functions suited for measurement applications.
