The NI PXIe-5632 is a full 2-port PXI Express vector network analyzer built for accurate and repeatable RF network analysis in automated test environments. Covering 300 kHz to 8.5 GHz, it supports complete S-parameter measurements, including S11, S21, S12, and S22, making it suitable for characterizing filters, amplifiers, attenuators, cables, passive devices, and other RF or microwave components. With 1 Hz frequency resolution, the PXIe-5632 is capable of both broad frequency sweeps and highly detailed narrowband analysis where fine resolution is important.
One of the strongest aspects of the PXIe-5632 is its flexibility in real measurement work. It supports linear sweeps, segmented sweeps, and power sweeps, with up to 20,001 measurement points, allowing engineers to optimize speed, resolution, and coverage depending on the device under test. The analyzer also supports a wide range of display and analysis formats, including log magnitude, phase, group delay, VSWR, impedance, real/imaginary, Smith chart, and power-domain views, which makes it useful for both basic pass/fail verification and deeper RF design analysis.
From a performance standpoint, the PXIe-5632 is well suited for demanding lab and production applications. The source covers the full 300 kHz to 8.5 GHz frequency range, with leveled output power down to -30 dBm and up to approximately +15 dBm at lower frequencies, decreasing slightly at the upper end of the range. The receiver architecture provides strong dynamic range, enabling meaningful insertion loss, return loss, and transmission measurements across a wide variety of DUTs. Low trace noise and stable vector accuracy help support reliable measurements in environments where repeatability matters.
The module is also useful for more advanced applications beyond standard passive component testing. It offers features such as frequency-offset capability for measuring frequency translation devices, along with support for automatic precision calibration, manual calibration workflows, and reference plane extension. These capabilities make it a practical solution for engineers working with mixers, converters, integrated RF assemblies, and automated validation systems where calibration control and measurement integrity are essential.
Because it is housed in a compact PXI Express 3U module, the PXIe-5632 is a strong choice for users who want true vector network analysis inside a modular platform instead of a standalone bench instrument. It integrates well into rack-based and manufacturing systems, while still providing the level of measurement functionality expected from a modern VNA. For organizations building automated RF test stations, the NI PXIe-5632 offers a strong balance of performance, integration, and throughput in a compact PXI form factor.
