I am interested in the ADC-40 which works on a 5 volt signal with 8 bit resolution. What isn't clear to me is if I choose a smaller signal range, say 20 millivolts, do I get 8 bit resolution over 20 millivolts or over 5 volts?
Second question: is the software the same for all scopes? I wanted to download a demo version, but it wasn't clear that I would be seeing what I would ultimately use. The question of interest was: can I choose ranges, time bases etc. Time bases I assume will run from 500 usec up to infinity, but this would clearly be dependent upon the scope. Thus the question of the software isn't clear.
