The Agilent/Keysight 5086-6974 and 5086-7974 are RF and microwave signal conditioning assemblies designed for integration into network analyzer systems and high-frequency test equipment. The 5086-7974 (A74 Switch Splitter) divides three input signals into separate signal paths, routing two directly to R1 and R2 samplers while the third path is switched through step attenuators, bias tees, and directional couplers. The 5086-6974 functions as a mixer/amplifier/detector assembly for RF and microwave measurement applications.
