Re: Isolating SnapAmp from KFLOP to remove motor noise

Hi Tom, I was able to overcome the noise issue in my UART line by using a BJT as a NOT gate to invert the signal before using an optocoupler (which inverts the signal again - back to normal), however I do still see the switching noise all over my system. I've put my isolation proposal on hold for th...

Re: Isolating SnapAmp from KFLOP to remove motor noise

Hi Tom, Thank you for your reply, I appreciate the help! For reference, here is more information on the grounding, earth grounding, power supplies, and shielding: The full setup consists of a KFLOP stacked on top of a SnapAmp with a KSTEP adjacent to them - connected via JP5 (RJ45 Connector). There ...

Isolating SnapAmp from KFLOP to remove motor noise

Hello! I've been working with the Dynomotion suite for the better part of a year now and have found most aspects to be robust and fairly straightforward. The only issue which has continued to crop up around our system is the ~30kHz switching noise from the SnapAmp which dirties up my IO wherever it ...
