ETF has the riders which has the waveforms in it on page 30. It's interesting to see that there's a 60hz signal on the sync output, that might explain the jittering. How much of a waveform should I realistically be getting on the power supply? I would have thought that the filter caps being as big as they are would have taken care of it.
