How to view QPPL and TTCrx state on a Controller Board

  • Log on a Controller Board with the " cc " login;
  • Go in the " CONTR_V3 " directory by taping " cd CONTR_V3 ";
  • Then run the script to view QPLL and TTCrx state by taping " Read_Board_Info_V3.1.py ". It returns several informations and among them you have:
    • the current state of the signals QPLL Locked, QPLL Error and TTCrx Ready;
    • an indication if the QPLL was temporarily seen in error or unlocked and if the TTCrx was temporarily not ready
  • If you want to clear the memory of an undesired state seen in the past you have to send a reset by running an other script by taping " Reset_QPLL_Monitoring.py "
