Step 1: Gain and offset

  1. Channel gain set to a reasonable low value;

  2. All bias set to zero nominal;

  3. Start data taking Mode 1;

  4. Increment bias with a rough step, go back to step 3 until end of bias scan;

  5. Increment gain until maximum gain compatible with the whole I-V curve is found. All temporary files produced at step 3 are analyzed by module MDaqFindBestGain and save in database.

At the end of this step for each channel define in profile a proper gain and offset value is saved in the database.
