10 . Tie the local input receiving the test pattern signal to the output to be
optimized.
11 . Use the test equipment or examine the displayed video image with a critical
eye to determine which video signal — red, green, or blue — is most shifted
to the left.
12 . Adjust the leftmost video signal to the right until all three colors are
converged.
N
When the skew adjustment is set to zero, the MTPX Plus cannot shift the
rightmost video image to the left.
N A 2-nanosecond adjustment is very fine. Up to 10 nanoseconds of delay may be
necessary before you detect a change in the display.
13 . If either of the two the remaining colors is left shifted, repeat steps 11 and 12 .
14 . Repeat steps 9 through 13 for all other outputs.
MTPX Plus Pre-Peak selection
N
MTPX Pre-Peak is available on the first 25% of the MTPX Plus outputs (for
example, outputs 1 through 4 for an MTPX Plus 168).
If the cable between the MTPX Plus and the receiver is > 300', turn the MTPX Plus’s
Pre-Peak feature on. For shorter cables, turn the feature off.
MTP Receiver level/peaking setting
If level/peaking is available on the connected receiver(s), adjust it as follows:
1 . If using an oscilloscope , apply a white field test pattern to one the local
(VGA) inputs on the MTPX Plus (figure 5-21).
If using a monitor , apply a Color Bars test pattern to one the local (VGA)
inputs on the MTPX Plus.
H The Extron VTG 300 or VTG 400 are recommended to provide the test pattern.
2 . Tie the local input receiving the test pattern signal to the output connected to
the MTP receiver to be optimized.

3 . Connect an oscilloscope or monitor to the output of the MTP receiver.
4 . Adjust the receiver’s level/peaking in accordance with the applicable MTP
product manual.
5 . Repeat steps 2 through 4 for each receiver to be optimized.
