    keyword=T1 trigger rate

    From the xscalar screen of R-arm, we find that T1 trigger rate is doubled compared to DAQ rate, while only T1 is included during the run and other triggers are with large prescaler factors. However, the T1 trigger is almost the same as DAQ rate in the xscalar screen of L-arm. This might be caused by after-pulse or jitter of T1. T1 signal sent to scalar needs to be checked when having a chance.
