The Keysight P9375B is a compact 2-port Vector Network Analyzer engineered for RF and microwave component characterization from 100 kHz to 26.5 GHz. Its faceless architecture eliminates the traditional instrument chassis, reducing footprint to 48 × 176 × 333 mm and weight to less than 2 kg while maintaining the measurement science, GUI, and SCPI command compatibility of Keysight’s high-performance VNA platforms. Control via Thunderbolt 3 to an external Windows 10 (64-bit) host PC enables rapid deployment across test locations and improved measurement throughput.
