Probe PSU output with 'scope again and 10X probe Use a AC mains scope as was available, means referenced to ground of AC, but should be ground of platform (and hence Fee64) Figs 1-3: Traces of PSU outputs (5V, -6V, 5V Return) with 10X probe, 1 MOhm impedance AC coupled Lots of fluctuation and jitter Figs 4-6: DC 1MOhm output from all 3 power rails Fig 7-8: Small "loop" using probe and observed scope spectra. After lunch ideas: - Try again with 1X probe attenuation, maybe record output to USB - Remove unconnected MACBs from master -
