This unit
The Agilent/Keysight 8720B is a microwave vector network analyzer engineered for RF and microwave component and system characterization from 130 MHz to 20 GHz. It combines a synthesized source, integrated switching S-parameter test set, and color display in a single instrument, enabling both forward and reverse S-parameter measurements with a single connection.
