I have done a lot of stuff with 1 RBW, without any problem, but wit great experimenters enthusiasm.
Resolving power of the instrument is simply extraordinary.
Maybe one question for analyzer experts:
SSA3000X is specified from 9kHz, but measurements is possible from 0Hz.
I have done some in audio range and have noticed that amplitude is attenuated,
everything else seemed to be fine.
Is it safe to measure so low frequencies ever, and when not why this is not blocked (in software?)?
Unfortunately, is not many stuff about that on the web?
