1 | Yes | 12/10/2014 |
| Ben 12/15/14: "Board 1 wasn't getting a link when Omar tested last week. When I run on my desk with the test firmware it works fine. I recommend we flash the normal firmware back and try again." | |
2 | No | - | - | - | FEB mezzanine Amtech connector has been replaced but the board does not have any rework done. |
3 | No | - | - | - | Waiting to be reworked. Initial test have shown that only 19/20 APV's can be synced. |
4 | No | 12/10/14 | - | - | Waiting to be reworked. Initial test have shown that, except for the edge channels, the noise on FEB CH 0-2 ranges from ~47-50 ADC counts. This is consistent with previous observations so these channels seem fine. There is a ripple in the noise present on FEB CH 03 and the noise across the whole hybrid is ~10 ADC counts higher than the rest of the channels. |
5 | Yes | 12/11/14 | 12/11/14 | Yes | It looks fine. |
6 | Yes | 12/11/14 | - | No | The baseline and noise of FEB CH 00 has issues. Most of the events had a baseline at ~6150 ADC counts and the noise was ~900 ADC counts. The behavior worsened in subsequent runs. |
7 | No | Waiting to be reworked. | |||
8 | Yes | 12/11/14 | 12/11/14 | Yes | This board looks fine. |

10 | Yes | 12/11/14 | 12/11/14 | Yes | After power cycling? everything looks fine now. |
11 | Yes | 12/10/14 | No | Again, overall the noise looks fine (~50 ADC counts) but there seems to be some samples that still have a large shift in the noise. Looking at the baseline distribution, there seems to be some large tails so that's probably the problem (ADC sampling point is off?). | |
12 | Yes | 12/11/14 | 12/11/14 | Yes | The baseline, once again, has tails but overall the noise looks fine on all FEB channels. The baseline and noise on FEB CH 1 and 3 have features similar to what we saw yesterday -- first sample noise is shifted by ~5-10 ADC counts. All other samples look fine. |
13 | Yes | 12/10/14 | A link to the FEB couldn't be established. Board 13 has some known issues on its D1.0V rail | ||
14 | Yes | 12/10/14 | 12/11/14 | Yes | Looks fine. |
15 | Yes | 12/10/14 | 12/11/14 | Yes | Baseline has tails and the shifts in the noise are present on the same APV's as before (on CH 1) but otherwise it looks fine. |
