Detector 1 anneal 2012

Notes

• There was a large spike in D1 on September 2 at ~07:16 UT.

 This caused the shutters to engage and the other detectors to spike as well

• 2014 May 17:
  • G1 rear fast threshold from 0x45 to 0x50
  • A short and negligible problem arose when it was intended to command detector 4, but used the command for G1, the "/IDPUTABLE[X]" command.  The error was caught, and the "bad" threshold setting was only in place for about 3 minutes. Entire commanding sequence is below.

    • 14-137-04:04:06  /IDPUTABLE1 OFFSET=REARFASTDAC
    • 14-137-04:04:24  /IDPULOAD VALUE=0x50

    • 14-137-04:04:31  /IDPUTABLE1 OFFSET=REARFASTDAC  (the load address was set to G1 not G4)
    • 14-137-04:04:39  /IDPULOAD VALUE=0x90   (and this was sent to G1 not G4 as intended)
    • 14-137-04:07:38  /IDPUTABLE4 OFFSET=REARFASTDAC
    • 14-137-04:07:43  /IDPULOAD VALUE=0x90   (G4 rear fast was set properly)
    • 14-137-04:07:51  /IDPUTABLE1 OFFSET=REARFASTDAC
    • 14-137-04:07:58  /IDPULOAD VALUE=0x50   (G1 rear fast was returned to 0x50)
    • 14-137-04:08:02  /IDPUDUMPTABL TABLE=DIBTBL1
