Yes, that would be my next try, though I have to build some suitable extensions for the probe tips in order not to remove the panel.
Merry Christmas,

If your RPG is the same as my 8660B the output is 2 square wave chains which lead and lag depending on the direction of travel. You can put your dual trace scope on the outputs and watch the wave forms as you turn the knob and see how the traces look. If they look OK then you might have some decoding chips not working properly.

The RPG (rotating pulse generator, i.e. the encoder) of one of my 3586A's doesn't work well. Clockwise it works well, counterclockwise it is erratic. May it be an issue in the encoder itself? I don't know how these encoders are made (are they optical?). May they fail this way? Before removing the front panel for troubleshooting, I wanted to ask the group for any advices. I could find one on ebay right now, but it would cost 50 USD + shipping.
Thanks,
