The HP/Agilent 8722ES is a 40 GHz S-parameter vector network analyzer delivering precise RF and microwave component characterization from 50 MHz to 40 GHz. Integrated synthesized source, test set, and tuned receiver architecture enables accurate magnitude and phase measurements across forward and reverse transmission paths. The instrument maintains 100 dB dynamic range and supports two-port, adapter-removal, and optional TRL calibration for measurement integrity in demanding component validation.
