MCA527
3 General mode = 'Timestamps recorder' (= 3, 4 or 5)
This file format is used by the 'Timestamps Recorder' computer program that operates the general modes
'Timestamps recorder (level triggered)' (= 3), 'Timestamps recorder (edge triggered)” (= 4) and Timestamps
recorder (analog high rate counting)” (= 5). Since the parameters of the these general modes differ only slightly,
an identical file format is used for these general modes. The basis file block contains however some
parameters that are only relevant for one of these general modes.
