There were no data links present. Looking at the
oscillator that is used to driver the links, the
frequency is at half of what is it suppose to be.
1/23/15 - TKN
Checked the grounding scheme of the detector.
L1-3 u-channel / SVT Box: 0.1 Ohms
FEB cooling plate / SVT Box: 6.7 Ohms
FEB cooling plate / table: 4.6 Ohms
SVT Box / table: 3.4 Ohms
Seems to imply that the table is between the FEB cooling plate and the SVT Box. Perhaps implies a connection from FEB cooling plate to vacuum box (e.g. via data cable edge contact) and then vacuum box to table then table to SVT Box?
We should try to break this when we can.
