PXI Module, RF Switch Matrix

The NI PXI RF Switch MUX Modules provide flexible and reliable RF signal routing for automated test and measurement systems. Designed to switch and multiplex RF signals between multiple instruments and devices under test, these modules enable efficient management of complex RF test configurations within PXI-based platforms. Built on the PXI Express architecture, PXI RF Switch MUX modules deliver low insertion loss, high isolation, and fast switching speeds while maintaining deterministic timing and synchronization with other PXI instruments. This ensures consistent signal integrity and repeatable performance across multi-channel RF systems. NI PXI RF Switch MUX hardware is widely used in wireless communications testing, semiconductor validation, aerospace and defense systems, and production test environments. The modular PXI form factor allows engineers to scale routing capacity as system requirements grow, reducing test time and improving overall system efficiency.
