An Offset value is provided after programming. A trigger starts the segment. 
The following segment advancement modes are available:  
  Auto: The segment is executed the number of times specified by its loop count. 
Then the last sample is played at the end.  
  Repeat: This advancement mode is quite the same like “Auto” with the difference 
that an advancement event is required at the end. 
  Single: An advancement event is required for each segment repetition. 
  Conditional: The segment is played infinitely after receiving a trigger. After being 
stopped (See SCPI command :ABORt[1|2]) the offset value is played.
