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
- The obvious starting point is the detector itself.
- The detector connects only to the slope box.
- 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.
- 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.
- There's also a single coax cable carrying HV from the slope box to the detector.
- There is a short cable from the detector to the slope box that contains three analog signals and some power/status connections.
- 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.
