Parameter
Numeric
*RST value
32, 0, 0, 0 (segment 1 = 32, segments 2, 3, and 4 = 0)
Specified Limits
0 to 65504
Description
Use this command to set up the number of bits within a segment. If a
segment is set to a length of 0, the segment will be skipped.
Restrictions:
At least one segments length has to be > 0.
The overall length of the pattern has to be <= 65504 and >= two times
segment length resolution.
If at least one segment is used to generate a PRBS, the overall pattern
length has to be <= 32768.
The segment length has a resolution that depends on the current set
frequency/period.
The segment at the start of a counted loop has a minimum length of 2
times the resolution.
NOTE
Every change of a segment length will cause the unused pattern data to
be overwritten (no undo!).
