Yes, that's where we reach the limits of my $150 scope.
You need a stable trigger for average mode.
But it doesn't manage to do that in the uV noise salad.
But I remembered that it has a line trigger mode (50Hz)
This works a little, but you can clearly see the limits.
In the attached screenshot: 1.02mV/div ("zoomed")
If you squint your eyes a little, you can see the capacitors discharging. :-DD
But for $150 it's not that bad... ;)

That's where 500uv/v scopes come in.
And you know, it's better to have a 150€ scope that allow us to "see" electricity that have nothing and just guess. I use 70 bucks toy scopes like the dso2512g and the dpox180h for quick checking signals and only use the better ones when I need more accurate info on what's going on.

Sure, but I can actually see enough. :)
Delving deeper into microvolts doesn't give me any additional information that could be of practical use at the moment.
obrigado

"De nada" :)
We're here to help each other :-+

If you increase the number of acquisitions in average mode, you see a pretty clean signal.
It's amazing what can be achieved with a few (cheap) tricks. :-+
