Agilent/Keysight 85107A

The Agilent/Keysight 85107A is a precision component within the 8510 network analyzer system that extends measurement capability into the microwave and millimeter-wave spectrum. Operating from 45 MHz to 50 GHz, it delivers S-parameter characterization of active and passive networks. Typically integrated with an 8510C vector network analyzer, synthesized sweeper, and test set, the 85107A provides the dynamic range and measurement fidelity required for demanding RF/microwave applications.
