THcTimeSyncEvtHandler Class Reference

Event handler to check TI and FADC synchronization.

Check syncronization of 4ns clock times recorded by the TIs and the FADCs. Also can be used to detect CAEN1190 TDC syncronization problems and write out a new coda file that corrects the synchronization. (These TDC synchronization problems were occuring in the spring of 2018.)

This event handler is typically not used in normal anlysis scripts. It is used with custom to check suspect runs and write synchronization corrected data files.

To use as a plugin, add to the analysis script:

THcTimeSyncEvtHandler *timesync = new THcTimeSyncEvtHandler("timesync","ADC/TI Time synchrnoziation")); timesync->AddEvtType(1); timesync->AddEvtType(2); ... gHaEvtHandlers->Add(timesync);

Assumes that all FADCs are in banks with the tag 250 and all TIblob banks are tag 4. And that these banks are contained without further structure in ROC banks. Also asssumes that the only banks containing banks are ROC banks.
