AIDA ADC & disc data synchronisation check |
|
|
Following analysis of AIDA ADC & disc readout ( see https://elog.ph.ed.ac.uk/AIDA/404 )
changed timestamp resolution from 1us/channel to 20.48us/channel
Offline sort (from disk file)
Attachments 1-3 s1-s32 # ADC data items per FEE64, s100-132 # disc data items per FEE64 (20.48us/channel)
Attachments 4-5 s1000 4 * ( module # - 1 ) + ASIC # versus timestamp (ch 0-95 ADC data, ch 100-195 disc data,
20.48us/channel)
Attachments 6-7 MIDASsort terminal session logs for *offline* sort
Online sort (from TapeServer)
Attachment 8 s1-s32 # ADC data items per FEE64, s100-132 # disc data items per FEE64 (20.48us/channel)
Attachments 9-10 s1000 4 * ( module # - 1 ) + ASIC # versus timestamp (ch 0-95 ADC data, ch 100-195 disc data,
20.48us/channel)
Attachments 11-12 MIDASsort terminal session logs for *online* sort
Attachment 13 MIDASsort FORTRAN sort routine sync.f
Attachment 14 Spectrum titles for the above sort routine
Note
1) data is discontinuous as a function of timestamp because we are sampling buffers
from the TapeServer rather than sorting all data as above
2) a low rate of timewarps is reported which appears to be an artifact of the buffer
sampling - no timewarps reported by analyses of the corresponding data files
