SCT Calibration Procedure

The SCT calibration should be performed in the steps listed below.

  1. Opto tests
    1. 2DBoc (several minutes for a crate)
    2. Rxthreshold (several minutes for a crate)
    3. Save configuration
    4. MSR (45 min for a crate)
    5. Save configuration
    6. Any module where the tests can not be finished should be put into the module history.
  2. Digital tests (optional)
    1. Pipeline (several minutes for a crate)
    2. Fullbypass (several minutes for a crate)
  3. Analog tests 1
    1. Strobedelay (several minutes for a crate)
    2. 3Pt Gain (about 30 min for a crate)
    3. If one crashes, exclude modules and perform both tests such that they complete up to the end. Include excluded modules in module history.
  4. Trimming (modules which have been verified as good by Step 3)
    1. Trimrange test where necessary (1.75 hours for a crate)
    2. Save configuration
    3. Response curve right afterwards (45 min for a crate)
    4. Save configuration
    5. Document failed modules in module history
  5. Analog tests 2 (modules which have been verified as good by Step 3)
    1. Responce curve (about 45 min for a crate)
    2. Save configuration
    3. If modules have to be taken out for the test, document it in the module history.
    4. Noise occupancy (about 30 min for a crate)
  6. Synchdoubletriggernoise test (several minutes for a crate)

For different temperatures step 5 is the most relevant.

Please DO NOT SHUTDOWN TDAQ software earlier than about 15min after the last test has been completed in order to allow enough time for the DB uploads to finish (Statusbar is being implemented).
