Creating a Waveform Sequence

A waveform sequence can contain up to 1,024 segments and have both segments and other
sequences (nested sequences). The signal generator lets you set the number of times the segments
and nested sequences repeat during play back. But there is a difference between repeating a
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.

Sequence B
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
1. Select the first segment:
a. Press Mode > Dual ARB > More > Waveform Sequences > Build New Waveform Sequence
> Insert Waveform.
b. Highlight the desired waveform segment and press Insert.
2. Select the second segment:
a. Highlight the next desired waveform segment and press Insert.
b. Press Done Inserting
