PXI将PCI Express集成到PXI标准中，可以满足更多的应用需求。

PCI Express技术可以集成到背板中，同时维持与现有系统的后向兼容性。

除了x1、x4和x8 PCI Express链路外，系统控制器插槽还支持高达x16的PCI Express链路，可以为PXI Express背板提供最高6GB/s的带宽。

利用PCI Express 技术，PXI Express将PXI中的可用带宽提高了45倍多，即从132MB/s提高到6GB/s;与此同时，还可以维持与PXI模块间的软件、硬件兼容性。

正是由于此性能的增强，PXI可以用于很多新型应用领域，其中很多领域在以前只能由昂贵的专用硬件实现。

图1. PCI Express技术提供每槽专属的更高带宽硬件架构PXI系统由三个基本部分组成——机箱、系统控制器和外围模块。

图2. 标准的8槽PXI机箱中，包括一个嵌入式系统控制器和七个外围模块PXI机箱PXI机箱为系统提供了坚固的模块化封装，通常为4槽、6槽、8槽、14槽或18槽的3U或6U机箱。

U(rack unit)是一种测量单位，用来描述安装在19或23英寸(指宽度)机架上的设备的高度。

1U等于44.45mm(1.75英寸)。

装在机架上的设备的尺寸大小通常用U来描述。

专用机箱还可在交流电源和直流电源中选择，以及是否集成信号调理功能。

很多PXI Express 机箱中都可以容纳PXI和PXI Express外围设备，而有些具有混合插槽的机箱(如NI PXIe-1075)，还可以容纳PXI Express外围设备或者兼容混合插槽的PXI设备。

利用这些机箱可以配置多种PXI系统从而满足应用需求。

该图片将PXI系统的机箱、控制器及PXI(e)外围模块与商用台式机组件进行了比较。

关键在于了解PXI的组成架构及其如何匹配商用PC技术：∙PXI机箱与台式机机箱的对比∙PXI控制器与台式机CPU、内存、I/O的对比∙PXI(e)外围模块与台式机PCI(e)外围模块的对比图 1. PXI系统与商用台式机的对比PXI(面向仪器系统的PCI扩展) 是一个基于PC的成熟平台，适用于测量和自动化系统。

它提供了电源、冷却和通信总线来支持同一机箱内的多个仪器模块。

PXI采用基于PC的商用PCI总线技术，但同时结合了坚固的CompactPCI模块化封装以及重要的定时和同步功能。

外围部件互连专业组(PCI-SIG)发布了PCI的进化版——PCI Express标准，显著提高了系统带宽。

负责管理PXI的PXI系统联盟(PXISA)采用了最新一代的商用PC总线技术，实现了PXI到PXI Express的演变。

PXI Express保持了PXI功能，以确保系统的向后兼容性，除了具有标准的PXI功能外，它还提供了更高的带宽、电源、冷却、定时和同步功能。

PXI和PXI Express拥有如此丰富的功能，看起来似乎非常复杂，但是，这些技术的核心是相同的：主流PC通信总线。

PXI和PXI Express机箱为当代工程师的测量和自动化系统提供了一个应用广泛的成熟架构。

由于PXI是由PXISA管理的开放式规范，任何厂商都可开发PXI产品。

为了更好地解释底层PXI系统细节，本文重点介绍了PXISA制定的PXI规范,以及这些规范如何在NI PXI硬件中得到体现。
