T EST P ATTERN FOR J ITTER
Choose the pattern to use for jitter measurements. Patterns 1 and 2 are short enough to treat as
a repeating pattern. Pattern 3, PRBS-31, is treated as a non-repeating pattern. Default is
Pattern 1 or 2.
QPHY-10GBase-KR Limit Sets
The default installation of QPHY-10GBase-KR contains only one test limit set, called “Default.”
In this script, limits are only used to convey Unit labels. The actual limits for each value tested
are encoded in or computed by the script and cannot be changed. The default limits used by
QPHY-10GBase-KR are specified in IEEE 802.3ap-2007.
