Included waves for all 12 FEEs

FEES 1, 5, 9 all show this HF noise on it, and are all located at the top of the AIDA mount. 
Connections: HV from DSSD (-ve) is in FEE9 
Pulser input is in FEE9 (non-inverted)

Resistance between FEE cooling plate and LEMO connector for all 3 FEEs is a few Ohms, as is resistance between copper braid on DSSD cable and the LEMO connector.

All FEEs show some noise but mainly those 3 and all four with DSSD. Will try to check DSSD connections in case something is messed up.

FEE layout for reference: (Beam&#39;s perspective)
