PXI chassis house PXI modules and controllers and connect them with a high-performance backplane that offers timing and synchronization capabilities. PXI chassis are compatible with PXI, PXI Express, and PXI hybrid modules.
The PXI backplane includes a common Reference Clock that you can use to synchronize multiple modules. It also offers capabilities such as a multidrop trigger bus and a matched trace length star trigger network for higher performance synchronization.
NI PXI chassis offer technology designed to increase cooling performance, improve the acoustical efficiency, and enhance the reliability of the power supply.
