The Keysight P9377B is a compact, 2-port vector network analyzer designed for RF and microwave characterization from 100 kHz to 44 GHz. This faceless, PC-controlled instrument connects via Thunderbolt 3 to an external Windows 10 computer, eliminating bench clutter while preserving the measurement science, GUI, and SCPI command compatibility of Keysight’s PNA Series VNAs. The P9377B delivers full S-parameter capability with 0.0015 dB rms trace noise (10 kHz IFBW) and a noise floor of −107 dB across its frequency span. It supports 2.4 mm female connectors and produces 8 dBm output power, making it suitable for passive component characterization and advanced time-domain analysis.
