What are the components of a PXI system？

The PXI system consists of three main hardware components:
Chassis, controller and module. Customizable system software can help you easily configure, intuitively display and automate measurement processes, analyze data and conveniently share reports.

Chassis
PXI cases are available in various sizes, with the number of slots ranging from 4 to 18
The chassis is the “skeleton” of a PXI system, equivalent to the mechanical casing and motherboard of a desktop computer. It can supply power to the system, provide cooling function and communication bus, and synchronize instrument modules. Depending on different size specifications, the case can be equipped with 2 to 18 slots. Whether you need a portable, desktop, rack-mounted or embedded system, the PXI case can meet all your requirements.

Controller
The integrated PXI controller contains everything needed to run a PXI system and does not require an external PC
The NI PXI controller offers two options: embedded and remote. The embedded controller contains all the functions required to run a PXI system without the need to connect to an external PC. The remote controller enables you to control the PXI system through a desktop computer, laptop or server computer.

Module
In a PXI system, each module itself is an independent instrument. NI offers over 600 types of PXI modules, with frequency ranges from DC coverage to millimeter waves. It covers standard instruments such as oscilloscopes and digital multimeters, data acquisition modules, and various interfaces including GPIB, serial and CAN buses. PXI is an open industry standard. Currently, over 70 different instrument suppliers offer nearly 1,500 related products.
