What's the scope background mean?
I'm looking at a really noisy signal on my yellow channel. Annoyingly noisy as the chip's analog power has an LC filter so it's SUPPOSED to be quiet, but that's not your problem.
I notice the background is colored a faded yellow kindof following the trace.
What does the background mean? I figure you wouldn't have drawn it dark yellow if it didn't mean something. Perhaps, "this signal is horribly noisy!" It is that.
(It's also like a 10th the amplitude I was expecting.)
Hello,
By default the scope channels are acquiring averaged samples of N ADC conversion, N = 100MHz ADC rate / sample rate
The sample rate is adjusted with time base, sample rate = 8000 (default device buffer size) / time base
Beside these samples a lower number and resolution Noise samples are also stored and shown as semitransparent band.
This, to indicate glitch or noise of higher frequency than the sampling rate.
To see more details on this noise band reduce the time base
