00.55 Observe high frequency noise in aida02 & aida04 ( n+n FEE64s ) - attachments 1-5
      and aida05 ( p+n FEE64 )
      frequency c. 5MHz

      Oscillation unchanged by

      HV cycle
      ASIC control load
      FEE64 power cycle
      BNC PB-5 pulser OFF
      BNC PB-5 pulser output disconnected from test + cable ( and remains disconnected )


      BB7 HV and preamp power OFF - oscillation disappears
      Note - BB7 HV and power have been on all day and AIDA was running OK until at least 22.18 11.12.23 - go figure!
