TP Skew Equalization
Skew exists between wire pairs when the physical length of one
wire pair is different from another. Skew affects the displayed image
when the difference in length between wire pairs exceeds 2 feet. The
difference in length causes the timing of the red, green, and blue
video signals to appear out of alignment (horizontal registration
errors). The signals transmitted on the shortest pair are shifted to
the left if you are using white lines on a black background. A white
vertical line on a black field can appear as individual red, green,
and blue lines that are close together; the signal transmitted on the
shortest wire pair leads the other colors and appears to the left on
the display. As the transmission cable length increases, the skew effect
increases.
The MTPX Plus input and output skew equalizer functions provide
separate time delay circuits on the red, green, and blue video lines.
This allows you to properly align the red, green, and blue video
signals on the displayed image. When correctly set, the red, green,
or blue video signal on the shortest wire pair is delayed to properly
converge the displayed video image.
UTP cable test equipment measures and reports wire pair length. The
report on the various pair lengths can be used to properly equalize
pair skew. If UTP cable test measurement cannot be done, pair skew
can still be equalized by viewing a crosshatch test pattern with a
critical eye.
