Keysight EXG and MXG X-Series Signal Generators User’s Guide 159Basic Digital Operation for N5172B/82B with Options 653/655/656/657Waveform Sequence SoftkeysCreating a Waveform SequenceA waveform sequence can contain up to 1,024 segments and have both segments and othersequences (nested sequences). The signal generator lets you set the number of times the segmentsand nested sequences repeat during play back. But there is a difference between repeating asegment versus repeating a nested sequence. Each segment can repeat up to 65,535 times, but nomatter how many times a segment repeats, it counts as a single segment. However each repetitionof a nested sequence counts as additional segments.The maximum number of times that a nested sequence can repeat is based on the number ofsegments in the nested sequence and the remaining number of allowed segments (1,024). Forexample, 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 sequenceEven though there is a limiting factor on the maximum number of times that a nested sequence canrepeat, each segment within the nested sequence can repeat up to 65,535 times.ExampleUse the following procedure to create and store a waveform sequence using one repetition each oftwo different segments.Assumption: The waveform segments are in BBG media (volatile memory).
