The Keysight (Agilent) E5053A Microwave Downconverter extends signal source analyzer frequency coverage into the microwave band by converting high-frequency signals to lower intermediate frequencies for processing by the E5052A/B SSA. This approach enables enhanced phase noise sensitivity measurement across microwave and millimeter-wave frequencies. The downconverter integrates directly into the SSA user interface, eliminating separate control software. For applications requiring coverage beyond 26.5 GHz, the E5053A works with Keysight 11970 series harmonic mixers to reach 110 GHz.
