(14) Sequence Repetition
If Trigger Sequence is selected, and if there is an entry in the Index Table whose Sequence
ROI Next Index is set to OFF, the value of Sequence Repetition is valid. Then, it becomes
possible to repeat the Index Table as set in Sequence Repetition.
After the acquisition sarts, the index table is executed from Index 0 by the external trigger.
And when the index table whose Sequence ROI Next Index is set to OFF is finished, the value
of Sequence Repetition is decremented internaly. In this case, if the result of decrement is
not "0", the index table starts from Index 0 again. If the result of decrement is 0, the status
changes to Acquisition Stop and cannot accept the external trigger.
The following chart shows the flow chart.
