(9) Repeat step (3).
(11) Measure time displacement of jittered
(10) Measure the period from start of sweep to
signal transition (fig. 3-5) and verify that
center of jittered signal transition (fig. 3-5) and
displacement (dynamic skew A) is 6.0 microseconds
verify that write/read skew is 8.89 microseconds
