Testbeam Electronics Status

U1BL refers to 1BL in the upper 32nd, D3BS2 refers to 3BS group 2 in the lower 32nd, etc

Send-ID means that we can set the chips to send-ID mode and read back sensible addresses in the data buffer. This is a test of both the TTC and the ROD patch panels.

Command RW means that we can set the chips to a threshold and read the same threshold back. This is a test of the TTC patch panel only.

Threshold Scans refers to the standard threshold ramps that we like to produce.

The numbers in the grid represent the number of chips that respond to a given test.

Needless to say, the specific chips that do not respond to a given command have been noted, and we are doing our best to map those to physical locations on the detector.
