Preselected Millimetre Mixer, 40-60GHz
Manufacturer's part number :
The Keysight 11974U mixer is preselected from 40 to 60 GHz to eliminate the need for signal identification. Preselection reduces mixer overload from broadband signals and reduces the interaction of local oscillator harmonics with the device under test.
Keysight 11974 Series preselected millimetre mixers extend the frequency range of the Keysight E4440A/46A/48A PSA Series high-peformance spectrum analysers, the Keysight E4407B ESA-E Series portable spectrum analyser, Keysight 8560 E-Series portable spectrum analysers, the Keysight 8566B spectrum analyser, and the Keysight 70000 series modular spectrum analysers.
The 11974U is not compatible with the N9030A PXA signal analyser.
