Introduction

Benefits of PXI

© National Instruments Corporation
The PXI (PCI eXtensions for Instrumentation) industry standard, an open
specification governed by the PXI Systems Alliance (PXISA), defines a
compact modular PC platform for test, measurement, and control systems.
PXI leverages the PCI bus, which is the de facto standard for today's
desktop computer software and hardware designs. As a result, PXI users
receive all the benefits of PCI within an architecture that supports
mechanical, electrical, and software features tailored to industrial
instrumentation, data acquisition, industrial automation, and control
applications.
Well-suited for industrial applications, PXI leverages the CompactPCI
specification, which defines a rugged form factor for PCI that offers
superior mechanical integrity and easy installation and removal of
hardware components. PXI products offer higher and more carefully
defined levels of environmental performance required by the vibration,
shock, temperature, and humidity extremes of industrial environments.
PXI adds mandatory environmental testing and active cooling to the
CompactPCI mechanical specification to ease system integration and
ensure multivendor interoperability.
Additionally, PXI meets the more specific needs of instrumentation users
by adding an integrated trigger bus and reference clock for multiple-board
synchronization, a star trigger bus for very precise timing, and local buses
for communication between adjacent peripherals.
