PXI Module, RF Vector Network Analyzer

The NI PXI RF Vector Network Analyzer (VNA) Modules deliver high-performance RF network analysis for characterizing components and systems across a wide frequency range. Built on the PXI Express architecture, these modules provide fast, accurate S-parameter measurements with deterministic timing and tight synchronization for automated test environments. NI PXI RF VNAs enable precise characterization of filters, amplifiers, antennas, cables, and RF front-end components. Their modular design allows seamless integration with other PXI RF instruments—such as signal generators, analyzers, and switches—supporting scalable, multi-port and multi-device test systems. Widely used in wireless communications, aerospace and defense, semiconductor validation, and RF component manufacturing, NI PXI RF Vector Network Analyzers support both R&D and production test workflows. The PXI platform enables high measurement throughput, repeatability, and long-term system flexibility as RF technologies evolve.
