PXI

PCI eXtensions for Instrumentation (PXI) is one of several modular electronic instrumentation platforms in current use. These platforms are used as a basis for building electronic test equipment, automation systems, and modular laboratory instruments. PXI is based on industry-standard computer buses and permits flexibility in building equipment. Often modules are fitted with custom software to manage the system.

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.

Executive Members of the alliance include Alfamation, Beijing Pansino Solutions Technology Co., CHROMA ATE Inc, GOEPEL electronic, MAC Panel, and Virginia Panel Corp. Another 56 associate member organizations that do not have voting rights are supporting PXI and use the PXI logo on their products and marketing material.

In 2006 two major players, Agilent Technologies and Keithley Instruments, entered the PXI test market.

The PXI worldwide market size, estimated in 2007, was 284 million USD and was expected to grow to over 520 million USD by 2010. The PXI market is also larger than the VME eXtensions for Instrumentation (VXI) market at an estimated size in 2007 of 233.2 million USD. The LAN eXtensions for Instrumentation (LXI) standard has grown to 200 million USD within 2 years..
