How big are the jumps? Are they all N x some integer ns ?
If so, then yes, I’ve seen Rb’s that do exactly that. The answer is a defective

I have tried opening up the enclosure I mounted the PRS10 in to cool it. I can measure the temperature of the case at about 40dC. Well below it's spec, I think. And, no, the 1PPS IN is not being used to discipline the outputs. I can send along a .tim file showing the jumps to anyone who is interested and sends me their email.
