A Vector Network Analyzer (VNA) is the gold standard for measuring the scattering parameters (S-parameters) of an RF or microwave device.

S-parameters provide a complete characterization of how energy is transmitted through and reflected from a network across a specified frequency range. Our VNAs offer high dynamic range, fast sweep speeds, and advanced error correction, which is critical for demanding applications like 5G, satellite communications, and radar.

For field engineers, the handheld VNA offers portability without sacrificing key measurement performance. Proper calibration using a quality calibration kit (e.g., SOLT, ECal) is essential to remove systemic errors and ensure the integrity of the measurement.
