Setting MTPX level/peaking
The simplest and surest way to set the input level/peaking is to
use the included MTP signal generator and the Auto-calibration
utility within the Matrix Switchers Control Program as follows:
N
To manually set the input level/peaking, proceed to step 7.
1. Disconnect the power and RJ-45 cables at the MTP
transmitter connected to the MTPX Plus input to be
adjusted.
2. Connect the two cables to the included MTP signal
generator.
3. If the input cable between the transmitter and the MTPX
Plus is longer than 300' (90 m), place the MTP signal
generator’s Pre-Peak switch on (up).

4. In the Matrix Switchers Control Program,
click Tools > MTPX Picture settings
and then click the Auto-Calibrate Level/
Peaking button.
After a few moments, the program reports whether or not
the calibration succeeded and the original and new settings
for the input level/peaking adjustment.
5. Disconnect the power and RJ-45 cables from the MTP
signal generator and reconnect them to the MTP
transmitter.

. Repeat steps 1 through 5 for each MTPX Plus input.
If, for any reason, you choose not to auto calibrate, or if
you want to fine tune the adjustment, you can manually
set the values as follows:
7. Connect an oscilloscope (preferred) or a monitor
(acceptable) to local output (VGA ouptut) 1.
8. If using an oscilloscope, apply a white field test pattern to
the input to be optimized via an MTP transmitter.
If using a monitor, apply a grayscale or Color Bars
test pattern to the input to be optimized via an MTP
transmitter.

The Extron VTG 300 or VTG 400 are recommended to
provide the test pattern.
9. Tie the input to be optimized to output 1.
10. Click Tools > MTPX Picture settings.
11. Observe the oscilloscope or the monitor with a critical
eye while you adjust the input level/peaking setting to
compensate for signal loss between the transmitter and the
MTPX.
12. If necessary, repeat steps 7 through 11 for each input.
