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.

The hybrid power monitoring and control now works through the hybrid GUI. It's mapped using feb index. Getting the physical name for it on the GUI is a little tricky but I'm working on it so until then you need to find out which feb nr you have powered (either from the non-zero hybrid currents that are updating, the temperature GUI or the daq GUIs).

10:00AM - PH
Testing L4b (serial #15) mounted on production plate placed on the test bench. Using one of the spare flanges that are not potted.The FEB ID is 2, data "DPM:channel" is 0:0, 0:1, 0:2 and 1:0. I see a few data link errors on 0:2. All hybrids sync. Took ~5000 events, file name is test.dat_000785.evio.0.

10:30AM - PH
Testing L1t (serial #01) with same setup as the L4b above. All hybrids sync. Took ~6400 events, file name is test.dat_000787.evio.0.

11:50AM - PH

There is a broken pin on L1t (serial #01). That particular one is not used. Retesting with same setup as the L4b above.  All hybrids sync. Took ~4800 events, file name is test.dat_000789.evio.0.
