PXI Architecture Breakdown - Chassis, Controllers & Instrumentation

PXI and the later evolution of the standard, PXIe are used for a host of test, instrumentation, control and data acquisition applications. This video asks what PXI is and looks at the various constituents, PXI chassis, controllers and the test or acquisition modules. PXI is easy to use and provides an easy to use modular form of instrumentation that can be customised to meet the requirements of virtually any test, control or data acquisition situation. PXI was developed out of the PCI bus and in fact PXI stands for PCI eXtensions for Instrumentation. The PXI standard was developed by National Instruments, but they passed its management over to the PXISA, PXI Systems Alliance, making it an industry standard. As a result modules chassis and controllers are available from a huge number of different companies globally. PXI chassis forms what may be called the backbone of the system providing power for the modules and connectivity to the rest of the system. The bus enables very tight synchronisation and triggering, essential for may of today’s test systems. It also enables huge amounts of data to be transferred very quickly across the backplane. Again this is needed for many test and data acquisition systems. The PXI controller may be an embedded controller in the rack, or it may be a module that links to an external computer. There are slots for many PXI modules. These instrumentation and control modules can be selected according to what is required. Thousands of different types of PXI module are available, enabling exactly what is needed to be bought and added to the overall PXI system. The PXI system may be programmed using a variety of different software packages - basically whatever is most convenient can be used.
