miv2k Posted December 27, 2022 Share Posted December 27, 2022 Hi, What do the two wide bands around the scoped graphs represent (in the left window)? Thanks! Link to comment Share on other sites More sharing options...
0 Anthocyanina Posted December 27, 2022 Share Posted December 27, 2022 That's the noise band, you can disable it by unticking the noise box in the channel settings. It is useful to have it on as it will show there can be some higher frequency content there miv2k 1 Link to comment Share on other sites More sharing options...
0 miv2k Posted December 27, 2022 Author Share Posted December 27, 2022 Thanks for the explanation. Is this the actual noise that the AD2 is observing, or some calculated one based on theoretical resolution? What I'm getting at is that the bands look really wide, and the signal on the other hand is very clean, look at the zoom for instance. With noise that big should I not see a lot of jagged lines in the capture? Link to comment Share on other sites More sharing options...

0 miv2k Posted December 27, 2022 Author Share Posted December 27, 2022 Got it now, thanks. So, ADC conversion frequency is way higher than the sampling frequency, for each sample AD2 manages to do a ton of conversions, which it normally averages (hence the smooth plot), but also shows min/max values in the form of this noise band to give an idea of what extremes the ADC saw while digitizing. attila 1 Link to comment Share on other sites More sharing options...
