Making Q-Check Jitter/Beta Measurements - Plextor PX-712UF Installation And User Manual

Section 4. Advanced Features and PlexTools Professional
NOTE: The TE/FE measurements are accurate only for a blank
recordable or rewritable DVD or CD. If you attempt to measure a
recorded or pre-recorded, commercially pressed DVD or CD, the
measurements have no meaning.

Making Q-Check Jitter/Beta Measurements

This function reports on the degree of beta and jitter on the CD or DVD
in the Plextor PX-712UF drive. This test is for use on a disc that
contains content—that is, a commercial pressed CD or DVD, or a disc
recorded on a CD or DVD drive.
To measure jitter and beta:
1. Place a pressed or recorded CD or DVD in the PX-712UF.
2. From the PlexTools menu bar, select Q-Check Beta/Jitter Test. You
see the Q-Check window with a graph for beta and jitter.
