DSSD stack will be as follows

1      3208-7  1019       125              upstream
2      3208-13 1020       120              downstream

First start checking bias pins on both detectors
These are pins on the *bottom right* of each 68 pin connector (C-2299)
Expect finite resistance

3208-7: 
  Top and bottom: 22 Ohm
  Left and right: 22 Ohm

3208-13:
  Top and bottom: 22 Ohm
  Left and right: 22 Ohm

Conclusion: All bias bond wires are intact on both DSSDs

Visual inspection is both DSSDs look good with no damage or bond wire issues
