CPS Sensors hooked up

We don't have triax connectors for our mock feed-thru, so we are using Class-A-ed flange feedthrus (ones which will actually be installed on BSC chambers).  We wired the in-vacuum, cables from Sensor to Feedthru  --->  and dirty/in-air cable from Feedthru to CPS Mini Racks on floor.  The mini-racks were then cabled together via 9-pin cables.

Bad Anti-Alias Box

While making initial checks for signals, noticed non-zero values for Corner1 Sensors.  This was traced to the Corner1 Anti-Alias Box (D1002693 s/ns1102693); toggled power, and switched its power supply cable and exhibited same issue.  It was removed, and Richard's crew found that we had a fried power regulator.  This was repaired and re-installed on the rack....BUT.... Richard mentioned that these anti-alias boxes were of a Rev where there could be heating issues.  To prevent overheating, electronics boxes were re-arranged in the rack to give the Anti-Alias boxes more space/air between them to prevent overheating.

Checked Signals For Sensors

After the Anti-Alias box was repaired, confirmed that all the Trilliums, GS13s, L4Cs, and CPSs are wired up correctly (this was confirmed by watching signals on an medm window).
