PXI Vector Network Analyzers (VNAs) are modular, high-performance test instruments designed for RF and microwave signal analysis in industrial and research applications. These compact, PXI-based solutions offer precise measurements of scattering parameters (S-parameters), enabling accurate characterization of components like filters, amplifiers, and antennas. Key features include wide frequency ranges, fast sweep speeds, and seamless integration with automated test systems (ATE). Ideal for aerospace, defense, and telecommunications, PXI VNAs combine the flexibility of modular instrumentation with the reliability of benchtop analyzers, streamlining validation and production testing.
