Agilent/Keysight 8722ES

The Agilent/Keysight 8722ES is a two-port S-parameter vector network analyzer spanning 50 MHz to 40 GHz, delivering magnitude and phase measurements in both forward and reverse directions. The instrument integrates a synthesized source, test set, and tuned receiver to achieve dynamic range up to 110 dB and trace noise below 0.15 dB across its frequency span. It performs full two-port calibration with adapter-removal and optional TRL/LRM techniques, supported by four display channels and configurable measurement automation.
