PVSS problems:

     Hardware problems:

  • Firmware problems: CAEN modules of same type sending values with different units: http://cern.ch/helpdesk/problem/CT370298
  • What is the refreshment time for different types of CAEN power supplies? See answer (.pdf format)

    Note: SY527 modules seem to have a refreshment time shorter than the one expected from the tests mentioned. Reading of 30 RICH HV channels (three 821P boards) demonstrates that this time is about 1.2 seconds or even shorter.
