The Agilent/Keysight 3702B is an IF/BB (Intermediate Frequency/Baseband) receiver designed for microwave link analysis systems. It isolates and characterizes intermodulation distortion in wideband FM microwave radio systems, supporting both analog and digital radio applications. The 3702B functions as a plug-in component within larger test system configurations, offering selectable baseband test tone combinations and dual signal interface capability.
