The initial question sounds daft, and perhaps the others are as well, but as it's been a while since I used the ADC11/12 (parallel connected) ...
Can I actually use the ADC 11/12 as an oscilloscope?
I mean, Picoscope software appears to run with the ADC, but you classify the ADC as a Data Logger (and that is what I bought it for).
Assuming the answer is at least a qualified Yes:
I see a quoted sample rate of 10 kS/s, shared across all channels.
Does kS/s mean 1000 samples per second?
If so, as I'm being asked to monitor two channels, this means 5kS/s for each channel. Yes?
What relevance / limitations is this imposing on the signals being monitored?
Presumably I won't see any changes if the duration of the change is less than a certain time (A), nor will I see at all accurately signals above a certain frequency (B).
Would you care to put numbers against A and B?
