Agilent/Keysight P9372B

The Agilent/Keysight P9372B is a compact, PC-based vector network analyzer delivering RF and microwave component characterization from 9 kHz to 9 GHz. This two-port instrument weighs less than 2 kg and connects via Thunderbolt to an external Windows 10 (64-bit) computer, eliminating the need for internal processing or front-panel controls. The faceless design prioritizes portability without sacrificing measurement capability - it delivers 0.0015 dB rms trace noise at 10 kHz IFBW and 8 dBm output power across dual 3.5 mm female test ports.
