Waveform Sequences
segment versus repeating a nested sequence. Each segment can repeat up to 65,535 times, but no
matter how many times a segment repeats, it counts as a single segment. However each repetition
of a nested sequence counts as additional segments.
The maximum number of times that a nested sequence can repeat is based on the number of
segments in the nested sequence and the remaining number of allowed segments (1,024). For
example, with a sequence that contains 24 segments and one nested sequence with 4 segments,
the nested sequence is limited to 250 repetitions:
24 + (4 ´ 250) = 1,024 maximum number of segments per sequence
Even though there is a limiting factor on the maximum number of times that a nested sequence can
repeat, each segment within the nested sequence can repeat up to 65,535 times.
Example
Use the following procedure to create and store a waveform sequence using one repetition each of
two different segments.
Assumption
: The waveform segments are in BBG media (volatile memory). For information on
loading waveform segments into BBG media, see
