system components.
GAIN adjustment:
Set the GAIN adjustment to the minimum (full CCW) setting. If using
the T2-CARX-S skew compensated receiver, make sure the delay settings
for R, G, and B are all at “0”.
Using the crosshatch test pattern, slowly increase the GAIN setting until
the vertical lines are nearly as bright as the horizontal lines. In general,
you will have to set the vertical lines a little dimmer than the horizontal
or you will have too much peaking.
You can check for over peaking by using the SMPTE color bars and
looking for two or three overly bright vertical lines at the beginning of
each color transition. If this occurs, back the GAIN pot off slightly.
Once you are happy with the EQ setting, set the delay skew if available.
SKEW adjustments (T2-CARX-S model only):
The object of the delay skew adjustment is to merge the separate red,
green, and blue vertical lines into a solid white line.
Using the crosshatch test image, identify the left most color in each verti-
cal line of the image.
Select the “Next” push buttons on the Twister to “toggle” to this color.
The LED for the selected color will light.
Now use the “Left” and “Right” push buttons as needed to merge this
color with the right most vertical line in the image. The color LED will
begin to fl ash when the left or right push button reaches the end of it’s
range. Setting are automatically stored after 5 seconds of no changes.
Then adjust the remaining color line to merge with the fi rst two lines.
Once you have adjusted the skew, use the burst pattern to fi ne-tune the
display phase adjustment.
These last two steps may be repeated to optimize the image quality.
