PXI系統(tǒng)組件
PXI系統(tǒng)由三個主要硬件組件組成：機箱、控制器和模塊。系統(tǒng)軟件是可重新配置且可定制的。
機箱是PXI系統(tǒng)的“骨架”，相當于臺式計算機的機械外殼和主板。機箱可為系統(tǒng)提供電源、散熱和通信總線，并支持同一機箱內(nèi)的多個儀表模塊。PXI使用了基于PC的商用PCI和PCI Express總線技術(shù)，同時結(jié)合了堅固耐用的CompactPCI模塊化封裝以及重要的定時和同步功能。根據(jù)不同的大小規(guī)格，機箱可配備4到18個插槽，無論用戶需要的是便攜式、臺式、機架式還是嵌入式系統(tǒng)，PXI機箱均可一一滿足。
PXI控制器分集成式控制器和遠程控制器兩種類型。集成式控制器包含運行PXI系統(tǒng)所需的儀器，無需連接外部PC；而遠程控制器則可讓您通過臺式機、筆記本電腦或服務器計算機控制PXI系統(tǒng)。

Achieve high precision, high efficiency and high speed test and measurement with NI PXI, the industry standard automated test and measurement platform. The NI PXI PXI system provides high performance modular instrumentation and rich I/ OS with dedicated synchronization and major software functions for test measurement applications ranging from equipment inspection to automated production testing. NI is an industry leader in PXI, offering a wide range of industry-leading products and services. For more than 40 years, NI has developed automated test and measurement systems that help engineers solve the world’s toughest problems.

NI led the formation of the PXI Standards Group to create PXI, an open standard where NI PXI hardware utilizes the latest technologies, combined with powerful multi-core processors, FPgas and other technologies, to increase measurement range and performance. The PXI architecture enables measurement synchronization across multiple modules or chassis,

PXI system components
The PXI system consists of three main hardware components: chassis, controller, and module. The system software is reconfigurable and customizable.
The chassis is the “skeleton” of the PXI system, equivalent to the mechanical shell and motherboard of a desktop computer. The chassis provides power, cooling, and communication buses for the system, and supports multiple instrument modules in the same chassis. The PXI uses commercial PC-based PCI and PCI Express bus technologies, while combining a rugged CompactPCI modular package with important timing and synchronization capabilities. Depending on the size specifications, the chassis can be equipped with 4 to 18 slots, whether the user needs portable, desktop, rack or embedded system, PXI chassis can meet one by one.
PXI controller is divided into two types: integrated controller and remote controller. The integrated controller contains the instruments needed to run the PXI system without connecting to an external PC; The remote controller allows you to control the PXI system from a desktop, laptop, or server computer.
