Extron electronic 68-1383-01 REV. E manual Mtpx Plus Pre-Peak Selection, Output skew

Output skew

1.Connect an oscilloscope (preferred) or a monitor (acceptable) to the TP output to be adjusted, via an MTP receiver.

2.Apply a crosshatch test pattern to one the local (VGA) inputs.

3.Tie the local input receiving the test pattern signal to the output to be optimized.

4.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.

5.Adjust the leftmost video signal to the right until all three colors are converged.

6.If either of the two the remaining colors is left shifted, repeat steps 4 and 5.

7.Repeat steps 2 through 6 for all other outputs.

MTPX Plus Pre-Peak Selection

NOTE: 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 longer than 300 feet, turn the Pre- Peak feature on the MTPX Plus to on. For shorter cables, turn the feature off.

MTP Receiver Level/Peaking Setting

If level/peaking is available on the connected receivers, 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 (see figure 73).

If using a monitor, apply a Color Bars test pattern to one the local (VGA) inputs on the

MTPX Plus.

TIP: 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 level/peaking on the receiver in accordance with the applicable MTP product manual.

5.Repeat steps 2 through 4 for each receiver to be optimized.
