Scanning encoder debounce on new scope

What a magic tool Oscilloscope is, right?

Darn tootin' right.

It's nice to finally use it as a diagnostic/testing tool. The scope has always been a mystery to me. I've always wanted to use one, but never had any electronics training. So it's slow; getting old and a worsening memory doesn't help, but help from you folk make it fun.

One thing is for sure, I wouldn't hire me to do this stuff.

Your waveforms seem to indicate that you might benefit from adjusting the trimmer capacitor on your probe(s).

I noticed that "rhythmic pulse" too. I figured it might be the breadboard.

I wanted to enjoy my scope for a few days before tweaking it and messing it up.

OK, if you just want to see squiggly lines on the screen :-)
But you're not going to mess it up. It's part of verifying that it actually works as it should.
Compensating the probe, or at least veryfying its compensation, should ideally be done whenever you move a probe from one channel to another - which is another great reason to use the color coded rings on the probes so that the same probe gets used on the same channel each time.

Without a properly compensated probe your scope will not display a "true" representation of the waveform and things like automatic risetime and peak-to-peak voltage measurements might be incorect.

I'm sure there's a section, close to the beginning, in the manual on how to perform the probe compensation.
