Agilent/Keysight P9372A

The Agilent/Keysight P9372A Streamline is a compact, USB-powered vector network analyzer purpose-built for RF and microwave component and system characterization. Operating from 300 kHz to 9 GHz across 2 ports with 4-port capability via cascading, the P9372A delivers dynamic range exceeding 114 dB at 9 GHz and trace noise below 0.003 dBrms at 1 kHz IFBW. Measurement speed reaches 14 ms per 201-point sweep, while temperature stability holds at 0.005 dB/°C up to 4.5 GHz.

The instrument connects via USB 3.0 to an external PC running Windows 7 or 10 (64-bit), leveraging familiar Keysight VNA software with a unified graphical interface. Calibration integrates with Keysight ECal and mechanical modules for rapid, accurate setup. At 1.9 kg and 176 × 48 × 333 mm, the P9372A fits lab benches and field deployments alike.
