Data File Format

TQDC2 Txt Data File Format

TQDC2 program constructs txt-file with following lines:

  • Ev <evNumber> <TAI_sec>.<TAI_ns>

  • Tdc <ch>: <tdcLeadTime>

  • Adc <ch>: <adcTime>; <sample1> <sample2> ... <sampleN>

where

  • TAI time: Precise arrival time of the trigger

  • ch: Channel number in range 0-15

  • tdcLeadTime: HPTDC time in 0.024/1.024ns steps from trigger (TAI time)

  • adcTime: Timestamp of the first sample in 8ns steps from trigger (TAI time)

  • sample: ADC sample in signed 16-bit integer

TQDC2 Raw Data File Format

Raw Data File Format is MPD Raw Data where MStream payload is TQDC16VS-E Data Format without first 4 32-bit words, e.i. it startted with 4th word Event timestamp, TAI seconds
