RE: Linear Power Supply or Battery on Mac Mini - pics

The rep rate on those transients is around 30 Hz. Wonder what is causing that? It's the same with the power supply and the battery.

Does the rep rate change with software changes? Does the same rep rate appear on the digital outs (e.g. SPDIF)? Can it be found on the analog output of a DAC? (At this stage it probably won't show up on a scope trace, but if one does an FFT on the output one might see it. One can find the right bin by taking an FFT of the power rail waveform.)
