The Keysight P9374A is a compact, USB-controlled vector network analyzer designed for RF and microwave component and system characterization from 300 kHz to 20 GHz. This benchtop instrument combines high dynamic range measurement capability with fast sweep speeds, making it suitable for production test, design validation, and laboratory applications across aerospace, defense, and wireless manufacturing environments.
Technical Specifications
The P9374A operates across a 300 kHz to 20 GHz frequency range with 1 to 6 Hz frequency resolution. The 2-port architecture (expandable to 4 ports with additional hardware) features 3.5 mm and SMA connectors at 50 Ohm impedance. Measurement speed reaches 14 ms for full 2-port calibrated sweeps, with dynamic range exceeding 115 dB at 6.5 GHz (10 Hz IFBW), 114 dB at 9 GHz, and 110 dB at 20 GHz. Trace noise measures 110 dB across full frequency span
