ZSUB patterns are PRBN patterns, where a number of bits are replaced by zeroes.
The zero substitution starts after the longest runs of zeroes in the pattern (for
example, for PRBN 2^7, after the run of 7 zeroes). This command allows you to
define the length of the run of zeroes. For example, to produce 10 zeroes in a PRBN
2^7 pattern, three additional bits after the run of 7 zeroes must be replaced by
zeroes. The bit after the run of zeroes (the closing bit) is set to 1.
The following figure shows an example, where a run of 10 zeroes is inserted into
a PRBN 2^7 pattern.
This command is only active when a ZSUB pattern has been selected (see “SENSe
[1]:PATTern[:SELect][?] ” on page 250).
The minimum value is the PRBN value - 1. The maximum value is length of the
pattern - 1. So, for a PRBN 2^7 pattern, the minimum value is 6, and the maximum
value is 127 (2^7 - 1).
