After having received a trigger, the selected segment or sequence is played (including
loop counts). After having selected a new sequence/segment, this sequence/segment is
played instead. Based on the timing relationship of the change request and the next
trigger, it is possible that the actually selected (old) waveform is played one more time,
before switching to the new one.
Limitations:
The trigger period must be bigger than the waveform length of the biggest
waveform including the loop counts.
The change delay from applying changes at the dynamic port to seeing them at the
output is the trigger to output delay (see datasheet) plus 256 sync clock cycles
minimum. Due to instrument internal functionality, this delay cannot be specified
exactly and it is always possible that one more segment/sequence A is played
before switching to B.
