Check Out Positioner Failing Phenomen

  • Charlie, Hrand and Matt looked into the reasons why some positioners were not working during some of the cold tests.
  • Previous investigations had shown that the positioners had a frequency of 0.0000 set.
  • It was not clear when and why this happened.
  • After restarting the system the error would occure sometimes and sometimes not.
  • Since Number 1 was not working at all before these actions (despite Msim restarts and setFrequenciesAll script) it is concluded that the failure lies outside of MSIM.
  • No further action to debug electronics since we are waiting on new FPGA version.
