11.8.3 Start and stop recording of third party devices including trigger indication pulses
In some instances it may be desired to have a trigger indication in the data, for example
using a manual trigger button, or using an external clock. The following example shows how
to do this.
Note: The trigger indication below has been indicated in this example as coming through via
the Sync In 2 channel, while start, stop recording and reset timer come through in the Sync
In 1.if Sync In 1 is also used for the trigger indication, one should additionally insert the
amount of pulses expected between the start and stop recording, therefore changing the
skip factor for stop recording to a large number equivalent to the number of pulses expected
between start and stop recording. If this is known, it can be very efficient, otherwise it may
be limiting. The example shows a simplified method, independent of time needed for
recording or number of trigger pulses expected.
