The Anritsu MS2025B is a handheld 2-port Vector Network Analyzer integrating VNA, Power Meter, and Vector Voltmeter functions into a single portable instrument. Operating from 500 kHz to 6 GHz, it delivers 100 dB transmission dynamic range and 95 dBm maximum dynamic range with full error correction including directivity and source match. Built for field deployment in aerospace, defense, and communications applications, the MS2025B enables rapid S-parameter characterization, cable phase matching via vector voltmeter, and distance-to-fault analysis. Its touchscreen interface and LAN connectivity support installation, maintenance, and troubleshooting workflows for antennas, cables, filters, amplifiers, and associated RF systems.
