This defines the minimum jitter amplitude step size. The test for one frequency
stops when this step size is reached.
For a description of this method refer to
For extended binary search, you can set the coarse and fine accuracy. The test for
one frequency stops when the BER limit is crossed with fine accuracy amplitude
steps.

“Extended binary search” on page 437
The minimum and maximum jitter curves have been introduced to speed up the
jitter tolerance characterization measurement by specifying lower and upper
boundaries for the search. This reduces the number of measurements needed.
Instead of starting and stopping the measurement at a fixed jitter level for all the
frequencies, it is possible to specify minimum and maximum jitter curves at which
the measurement starts and stops depending on the search algorithm. This avoids
measuring points where the DUT is known to operate. If for a particular frequency
the starting point fails, then the search algorithm reverts to the minimum jitter level
to start the search for that frequency. The next frequency step will start based on
the minimum curve again. This gives a complete picture of the jitter tolerance even
if the start values are not carefully selected.
The format used to specify the minimum and maximum jitter curves are same as
that of existing jitter compliance file. See
“User-Defined Standards” on page
