Agilent/Keysight P9375A

The Keysight P9375A Streamline is a compact, USB-controlled Vector Network Analyzer for PC-based RF and microwave component testing. Operating from 300 kHz to 26.5 GHz, it delivers dynamic range to 122 dB with trace noise below 0.003 dBrms at 1 kHz IF bandwidth. The instrument combines fast measurement speed - 24 milliseconds for 201-point sweeps with full 2-port calibration at 100 kHz IF bandwidth - with the same measurement science and GUI as Keysight's higher-performance VNAs.

Its compact footprint (176 mm × 48 mm × 333 mm) enables easy relocation between test stations and integration into automated test systems. Two standard ports expand to four ports maximum, with 3.5 mm, SMA, or SMB connectors depending on configuration. Output power ranges from -40 dBm to +7 dBm, with selectable IF bandwidths of 10 Hz, 1 kHz, or 100 kHz.

The P9375A supports all Keysight Electronic Calibration modules and mechanical calibration for flexible, accurate calibration workflows.
