Cable Plant Testing

Testing the cable plant requires the ability to break the system apart at critical junctures to measure and/or inject signals, but to do so in a way that is not physically difficult, particularly disruptive or fraught with risk.

Understand the pieces

1. The obvious starting point is the detector itself.
2. The detector connects only to the slope box.
   1. There is a short cable from the detector to the slope box that contains three analog signals and some power/status connections.
      • This is the Ge link.
   2. There is a short cable from the detector to the slope box that contains seven analog signals and some power/status connections.
      • This is the BGO link.
   3. There's also a single coax cable carrying HV from the slope box to the detector.
3. Physically accessing any of these connections is difficult as the detectors are mounted in a whole bunch of odd positions.
   • There is a history of problems with the coax connections backing out of the connector shells.
