HP/Agilent 11974 Series Preselected Millimeter Mixers
11974 Series preselected millimeter mixers are available to extend the frequency range of
analyzers with Option AYZ (external mixing) up to 75 GHz. Preselection reduces mixer
overload from broadband signals, reduces radiation of local oscillator harmonics back to
the device under test, and reduces the level of image and multiple responses displayed.
