Input MTP settings
Each R, G, and B channel can skew up to 62 nanoseconds total (2 nanoseconds per step,
31 steps total).
To set the input skew:
1. Connect an oscilloscope (preferred) or a monitor (acceptable) to the VGA output of
the MTP/HDMI U R receiver.
2. Apply a crosshatch pattern to the input to be optimized.
3. 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.
4. From the View menu in DSP Configurator, select Video I/O to open the Video I/O
workspace. Alternatively, press <F4>, or click Video I/O in the Legend section of
another workspace.
5. Double-click the MTP block for input 4. The Input MTP Settings dialog box opens.
6. In the Skew section, click the Up and Down arrows or enter a value into the R, G,
or B fields to adjust the skew setting of the leftmost video signal towards the right
until all three colors are properly converged.
7. Click OK.
To set the input level and peaking:
1. Apply an RGB source signal to input 4 and select that input.
2. Connect an oscilloscope (preferred) or a monitor (acceptable) to the VGA output of
the MTP/HDMI U R receiver.
3. Apply the necessary test pattern to the input to be optimized via an MTP transmitter.

4. From the View menu in DSP Configurator, select Video I/O to open the Video I/O
workspace. Alternatively, press <F4>, or click Video I/O in the Legend section of
another workspace.
5. Double-click the MTP block for input 4. The Input MTP Settings dialog box opens.
6. Observe the oscilloscope or monitor with a critical eye while you adjust the input level
and peaking settings to compensate for the signal loss between the transmitter and
the MTP/HDMI U R receiver.
7. To adjust the input level, click and drag the Level slider handle or enter a value in the
field below the level.
8. To adjust the peaking, click the Up and Down arrows or enter a value in the Peaking
field.
