Front-end electronics Calibration

Front-end electronics Calibration. Pedestal - FADC 내부 함수 이용 : new run 시작전 항상 측정  mean 값만 측정 됨 - external trigger 이용 : trigger box 에서 random trigger 생성  주기적으로 수행 : mean 값과 rms 측정. 2. Timing calibration - 각 보드에 대한 T0 calibration : function generator 이용.

  1. Front-end electronics Calibration • Pedestal • - FADC 내부 함수 이용 : new run 시작전 항상 측정 •  mean 값만 측정 됨 • - external trigger 이용 : trigger box에서 random trigger 생성 •  주기적으로 수행 : mean값과 rms측정

  2. 2. Timing calibration - 각 보드에 대한 T0 calibration : function generator 이용 FADC 1 FADC 2 FADC 3 FADC 4 a b d c FADC 1 을 기준으로 하면 T2calib = T2 – ( b – a ) T3calib = T3 – ( c – a ) T4calib = T4 – ( d – a ) …..
