(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

maximum.
