The Agilent/Keysight 8712C is a vector network analyzer spanning 300 kHz to 1.3 GHz, designed for RF component characterization and system-level testing. This single-unit instrument integrates a synthesized RF source, transmission/reflection test set, dual-channel receivers, and CRT display to deliver S-parameter, impedance, and SWR measurements in production and lab environments.
