The Agilent/Keysight E5053A is a microwave downconverter that extends the frequency measurement range of the Keysight E5052A/B Signal Source Analyzer. This instrument enables phase noise characterization of microwave and millimeter-wave signals through cross-correlation measurement techniques. The E5053A integrates directly with the E5052A/B user interface, providing enhanced phase noise sensitivity across extended frequency bands. For measurements beyond 26.5 GHz, the E5053A operates with Keysight 11970 series harmonic mixers to achieve phase noise analysis up to 110 GHz.

– Compatibility & Integration
The E5053A interfaces exclusively with the Keysight E5052A/B Signal Source Analyzer platform. Connection requires RF cables (Keysight part numbers E5053-61621 or E5053-61622), USB connectivity (part number 8121-0770), and BNC interconnects (part number 8120-1839). Harmonic mixer functionality requires Keysight 11970 series components for frequencies above 26.5 GHz.
