After putting in a truckload of electrolytics to get rid of ripple
in the race I have some residual noise in X 10 mode. I am wondering
if it might be almost normal.

In normal the trace is nice and sharp, but in X 10 it is about 0.8 mm. high.



** Completely normal for a 50MHz scope.

The 1Mmohm impedance and wide bandwidth combine to create about 150uV of noise which makes the trace a bit fuzzy at the high gain setting.
