Revision as of 14:09, 5 March 2021
Daisy chain tests of second DDC232 prototype in D109
Aim: Debug "mirroring" issues when daisy-chaining more than 2 DDC232s boards.
Notes
- DDC232 boards have a numerical identifier:
- Board 1: S1337-16BR photodiodes
- Board 2: 1k ohm resistors
- Board 3: S1227-16BQ photodiodes
- Board 4: S12915-16R photodiodes
- In the runs listed, boards are listed right to left, with the right-most board connected to the FPGA.
- In all runs, an integration time of 170us and full-scale range of 350pC is used.

| Run | Board Configuration | Description | Thumbnail |
|---|---|---|---|
| 1 | 3, 1 | Rotation of boards followed by swept covering of a few photodiodes in turn with black cloth. Boards initially facing downwards but rotated upwards to expose to room lighting. Sweep begins around 20s mark. Note that there is no mirroring and both boards behave as expected. |  |
| 2 | 3, 4 | Rotation of boards followed by swept covering of a few photodiodes in turn with black cloth. Boards initially facing downwards but rotated upwards to expose to room lighting. Sweep begins around 10s mark. Note similar behaviour to above. |  |
| 3 | 3, 2 | board rotation and sweep covering of photodiodes |  |
| 4 | 3, 1, 4 | board rotation and sweep covering of photodiodes |  |
| 5 | 3, 4, 1 | board rotation and sweep covering of photodiodes |  |
| 6 | 3, 4, 1 | swept exposure of photodiodes |  |
| 7 | 3, 4, 1 | reversed swept exposure of photodiodes |  |
| 8 | 4, 3, 1 | board rotation and sweep/finger covering of photodiodes |  |
| 9 | 3, 4, 2 | board rotation and sweep covering of photodiodes |  |
| 10 | 3, 2, 4 | board rotation and sweep covering of photodiodes |  |
| 11 | 3, 1, 4, 2 | board rotation and sweep covering of photodiodes |  |
| 12 | 3, 4, 2, 1 | board rotation and sweep covering of photodiodes |  |
