Noise studies - scope traces

These are for ch16, which shows the largest amount of 4MHz pickup.

Noise 1950V, 90/10 premix
Noise - zoom on 4MHz - 1950V, 90/10 premix

After connecting the preamp ground to the preamp end of the cable shielding

Noise - cable shield connected to preamp ground, 1950V, 90/10 premix
Noise - zoom on 4MHz - cable shield connected to preamp ground, 1950V, 90/10 premix
