busted LDOs -- AC |
| 2020-08-31 00:00:00 |
|
Resistance behind LDO3 to gnd 162 Ohms instead of ~1800 Ohms -> something else broken |
| 2020-09-14 00:00:00 |
|
DB successfully replaced the burnt LDOs, module working again |

|
SCA-C is broken. details TBW. K.O. |

|
SCA C, cannot see waveform (clamped to ADC min or ADC max). K.O. |

|
SCA C read clock is unconnected across the flex cable. K.O. |

|
clocks: SCA-A R=ok, W=largeamp; SCA-B R=sawtooth, W-ok, SCA-C R=sawtooth, W=0V, SCA-D R=ok,W=ok. K.O. |

|
SCA-D does not see the test pulse (via udaq-pwb). K.O. |

|
clocks: SCA-A W=ok, R=largeamp; SCA-B W=sawtooth, R=ok, SCA-C W=sawtooth, R=0V, SCA-D W=ok,R=ok. K.O. |

|
temporary repair of SCA-C read clock (jumped from SCA-D read clock). All SCAs work now. Permanent repair still needs to be done. K.O. |
| 2020-10-11 00:00:00 |
|
SCA D SPI interface not working (clk and enable are ok, nothing of data in and data out). Cannot control gain, cannot enable test pulse. K.O. |
| 2021-09-10 00:00:00 |
|
SCA-C bad temperature. K.O. |
