Unbonded channel (hybrid)

Normal

Cal-only run: Hybrid 17t, test 1

Full T0 run: Hybrid 0t, test 1

Noise: 15-20 ADC counts

Bonded channel (half-module)

Normal

Cal-only run: Half-module 5, test 7
Full T0 run:

Noise: 30-40 ADC counts with bias, ~80 ADC counts without bias

Defects

Unbonded channel: looks like an unbonded channel (low noise, long Tp and high response)
Pinhole: zero response, low noise
Partial pinhole: zero response, high noise (only appears with bias)
Unknown (wires touching?): Half-module 4, channels 317 and 319 - half response on two adjacent channels

Weird stuff

"DAQ noise" - Common-mode noise that shows up in readout-order-adjacent channels: Hybrid 4t, test 1 Half-module 1, test 3

"Noise hump" - uncorrelated noise only on the inner channels: Half-module 16, test 6
