Manually Setting the MTPX Level and Peaking
If you choose
not
to auto calibrate, or if you want to fine tune the adjustment, you can
manually set the values as follows:
1.
Connect an oscilloscope (preferred) or a monitor (acceptable) to local output
(VGA ouptut) 1.
2.
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.
TIP:
The Extron VTG 300 or VTG 400 are recommended to provide the test
pattern.
3.
Tie the input to be optimized to output 1.
