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
