Sorry for the confusion – I forgot about the processing gain of the FFT (I can see how a fast 14-bit ADC + FFT gain could get you there). Still another question – is the 110 dB dynamic range spur-free dynamic range across the entire 20 GHz range? If so, what are the conditions for this measurement (RBW, input signal levels, etc)? Sorry for the questions – I wish I had been at IMS2017 and would have asked the questions in person! The SM200A performance certainly appears very astonishing given the price point of < $12k.
