PXI system Components Component Introduction Photograph
Chassis The chassis is the "skeleton" of the 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. According to different size specifications, the chassis can be equipped with 2 to 18 slots, whether you need portable, desktop, rack mounted, or embedded systems, the PXI chassis can meet all your needs.
Controller The NI PXI controller offers two options: embedded and remote. The embedded controller contains all the functions required to run the PXI system without the need to connect to an external PC, while the remote controller allows you to control the PXI system through a desktop, laptop, or server computer.
Module In the PXI system, each module is itself an independent instrument. NI offers over 600 PXI modules with frequency ranges ranging from DC coverage to millimeter wave. 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, with over 70 different instrument suppliers currently offering nearly 1500 related products.
NI Software NI PXI and automation software can help you test more products in a shorter amount of time.
PXI Instrument Kit Beginner's Guide The PXI instrument kit is a pre configured set of NI's most popular high-quality instruments. Each kit includes a PXI module and is located in the 5-slot Thunderbolt ™ In the controlled PXI chassis, it can help you easily get started.
