PXI Module, RF Switch

The NI PXI RF Switch Modules provide reliable, high-performance RF signal routing for automated test and measurement systems. Designed to connect multiple RF instruments and devices under test, these modules enable flexible switching configurations that reduce test time and improve system efficiency. Built on the PXI Express architecture, NI PXI RF switches deliver low insertion loss, high isolation, and fast, repeatable switching while maintaining deterministic timing and synchronization with other PXI instruments. Their modular design supports a wide range of switch topologies, making them well suited for scalable RF test architectures. NI PXI RF Switch Modules are widely used in wireless communications testing, semiconductor validation, aerospace and defense systems, and production test environments. By enabling automated RF routing within PXI systems, they help engineers build repeatable, high-throughput test solutions that adapt to evolving RF requirements.
