Hi You really need to know a few things about the Rigol spec:
1) Is it simply a noise measure? If so, at what bandwidth and frequency (narrow will always be lower)? 2) Is it a signal spec? If so with what signal level and settings? Does it include / exclude IMD / harmonics? 3) Is it the spec on the number of screen divisions? (yes, I *have* seen that one) 4) Is it the just spec on the SFDR of the ADC? (assuming it's an ADC -> FFT beast) Without some qualifiers, the big print spectrum analyzer spec's don't mean a whole lot…. Bob On Jul 4, 2013, at 3:56 AM, Mark C.
