Agilent/Keysight 8714B

The Agilent/Keysight 8714B is a vector network analyzer for RF and microwave component characterization from 300 kHz to 3 GHz. It integrates a synthesized source with transmission/reflection test set, delivering S-parameter analysis, insertion loss, impedance, and group delay measurements across two independent channels. System dynamic range exceeds 100 dB in transmission mode, with real-time sweep speeds of 40–50 ms per sweep.
