Thus the number of samples between bunches in the bunch train may be not integer numbers which will be show up for long bunch trains.
839 +* {{code language="none"}}number of samples{{/code}}: total number of samoles recorded for each 10 Hz trigger
840 +* {{code language="none"}}error (ADC):{{/code}} 0 indicates that there was no error
841 +* {{code language="none"}}/CH0-CH3/offset{{/code}}: To use the full dynamic range of the ADC one can shift the base line . This offset is saved here.
842 +
843 +===== MHz ADCs =====
844 +
845 +similar to the GHz ADCs the MHz ADCs are saved with HDF5 names like:
846 +{{code language="none"}}/FL2/Experiment/MTCA-EXP1/SIS8300 100MHz ADC/CH2/TD{{/code}}
847 +DOOCS prop : FLASH.FEL/ADC.SIS.FL2EXP1/FL2EXP1.CH02/CH00.TD
848 +DAQ channel: : FLASH.FEL/ADC.SIS.FL2EXP1/FL2EXP1.CH02
849 +
850 +In addition there are also additional parameters saved like:
851 +
852 +* {{code language="none"}}sample frequency{{/code}}: it shows the sample frequency in MHz (number of samples per µs). NOTE: the clock of the ADC is NOT synchronized to the FLASH timing system. Thus the number of samples between bunches in the bunch train may be not integer numbers which will be show up for long bunch trains.
853 +* {{code language="none"}}number of samples{{/code}}: total number of samoles recorded for each 10 Hz trigger
