It provides power, cooling, and a communication bus to the system, and synchronizes the instrument modules. Chassis range in size from two to 18 slots to fit the needs of your application, whether you require a portable, benchtop, rack-mount, or embedded system.

2024年8月14日 · PXI (PCI eXtensions for Instrumentation) is a proven PC-based platform for measurement and automation systems. It provides power, cooling, and a communication bus to support multiple instrumentation modules within the same enclosure.

PCI eXtensions for Instrumentation (PXI) is one of several modular electronic instrumentation platforms in current use based on the Peripheral Component Interconnect bus, which includes PCI Express (PCIe). These platforms are used as a basis for building electronic test equipment, automation systems, and modular laboratory instruments.

PXI结合了PCI（Peripheral Component Interconnection-外围组件互连）的电气总线特性与CompactPCI（紧凑PCI）的坚固性、模块化及Eurocard机械封装的特性发展成适合于试验、测量与 数据采集 场合应用的机械、电气和软件规范。 制订PXI规范的目的是为了将台式PC的性能价格比优势与 PCI总线 面向仪器领域的必要扩展完美地结合起来，形成一种主流的 虚拟仪器 测试平台。 这使它成为测量和自动化系统的高性能、低成本运载平台。 [1] PXI在1997年完成开发，并 …

2025年1月6日 · PXI uses the high-speed Peripheral Component Interconnect (PCI) bus, which is the de facto standard driving today’s desktop computer software and hardware designs. PXI combines the PCI electrical bus with the rugged modular Eurocard mechanical packaging of …

PXI tracks the PCI bus standard, as it provides the fundamental electrical and software protocol element of the connectivity system.

2022年5月25日 · PXI的机箱有两种Trigger bus，分别是PXI Trigger和Star Trigger,其中Star Trigger 还分为单端和差分（D-Star Trigger）。 图 1 PXI Trigger和Star Trigger. PXI Trigger分为8个line，可以分别配置Trigger信号路由的方向（18槽机箱）。 图 2 PXI Trigger. Star Trigger是从时钟槽展开的，需要时钟卡才能使用。 图 3 Star Trigger. 3. 不同类型Trigger Bus的性能. 从性能上说，PXI Trigger槽位离得越近延时越低，而Star Trigger则不受槽位的距离的限制，延时几乎相同。

PXI Express offers the lowest latency of all mainstream commercial test and measurement bus technologies, delivering latency comparable to – and in some cases better than – PCI-based PXI. Also, PXI Express latency is several orders of magnitude better than the latencies of external buses such as USB or Ethernet.

2023年11月7日 · What is a PCI bus and how will it impact my PXI system? Solution To maintain signal integrity, a PCI bus signal can only propagate around 8 PXI slots for 33MHz signaling or 5 slots for Compact PCI 66 MHz signaling.

Refer following for the difference between PXI and LXI. PXI interface. Following are the details of PXI interface: • Full Form: PCI eXtensions for Instrumentation • It is based on PCI bus architecture. • Utilizes central processing model of the PC • It's size is module dependent. • The modules will have inter-connection overheads.
