Scanning encoder debounce on new scope

[Demon]

Before compensating, the probes had a slight up-tick/down-tick when changing edge:




That is now gone, so I must have done something right:



Yellow, encoder A
Blue, encoder B
Beige encoder A after Schmitt trigger
Green encoder B after Schmitt trigger


But there is still some static that cycles through at a regular rhythm. Here it is at a slower rate so it's more apparent:




This could just be an artifact on the USB port (have that static on PC USB port and external hub). I'll have to test on another 5 VDC power source.
