The R&S FSU67 is the first spectrum analyzer with a direct frequency range to 67 GHz and fundamental mixing. It allows measurements to 67 GHz without using cumbersome setups with external mixers.
This results in:
Simplified test set-ups with just one connection from 20 Hz to 67 GHz
Full span sweep of 67 GHz
Unambiguous frequency indication without the image response and multiple responses known from external harmonic mixers
Wider level range with a much higher allowable reference level than with harmonic mixers
Good level accuracy to 67 GHz
Low noise floor: -152 dBm (1 Hz) at 2 GHz, -130 dBm (1 Hz) at 65 GHz
