PXI systems provide high-performance modular instruments and other I/O modules that feature specialized synchronization and key software features for test and measurement applications from device validation to automated production test. In a PXI system, a chassis provides power, cooling, and a communication bus for modular instruments or I/O modules. You can control these modules from either an embedded controller or an external PC, using one or several of NI’s specialized engineering software tools to customize your system.

PC-Based Platform for Test, Measurement, and Control— PXI is the industry-leading modular instrumentation platform used to build compact, high-performance automated test systems. The measurement hardware is housed in an industrial chassis that can run as an embedded system or be tethered to a PC through a cabled interface. Benefits specific to PXI include increased channel count, portability, and integrated timing and synchronization.
