The recommended replacement product is the OML Inc. model S15MS-AG millimeter-wave source module with an E8257D PSG analog signal generator.

The Agilent 83557A millimeter-wave source module, one of a series of Agilent millimeter-wave source modules, can be driven by a variety of Agilent microwave sources providing millimeter-wave test signals for waveguide bands from 50 to 75 GHz. In addition, the Agilent 83557A millimeter-wave source module offers leveled high output power, full waveguide band frequency coverage, and the high frequency accuracy and resolution of the driving microwave source. Leveled output power from the Agilent 83557A is rated at +3 dBm and can permit the source module to serve as a mixer LO in some applications and also expands the available dynamic range in frequency response measurements.

Features:

• 50 to 75 GHz frequency range
• High accuracy and resolution
• Leveled high output power
• Can be driven by many Agilent microwave sources
• Low entry cost
