Yesterday the sum/inverter was found to be a considerable source of noise in the system.
Plugging it into an oscilloscope this morning it was clear there was a Vpp 17mv 60kHz sin wave in its signal - attachment 1 yellow trace

Looking through the merger messages from the nightshift we see bad timestamps in FEE 11. This FEE does not have any scalers going into it.
