Test Pattern
Choose the desired internal test pattern to display, or select OFF to turn OFF a test pattern. Alternatively, use
the
key for cycling through test patterns.
Test Pattern Grey Level
Set the desired level of gray for displaying in the full gray field test pattern.
Freeze Image
Enter a check mark to freeze (stop) an image at a single frame. This diagnostic tool is useful if you need to
examine in detail a still version of an incoming image that cannot be "frozen" at the source. For example, in
moving images it is sometimes difficult to observe artifacts such as external deinterlacing/resizing and signal
noise. Remove the check mark to return back to normal.
Color Enable
Select which color or colors you want to see. This is useful while working with color temperature, input levels
or other special setup parameters. Colors can also be enabled/disabled by entering the corresponding function
code listed on the back of the standard remote keypad.
Odd Pixel Adjustment
NOTES: 1) Factory-set and rarely required by user. 2) Source must be >90 MHz.
When using certain RGB sources, you may need to adjust the normal gain or offset of odd pixels in relation to
even pixels. This smooths out very narrow (1-pixel wide) "checks" or vertical stripes that indicate adjacent
"on" and "off" pixels. Although Offset and Gain slidebars can be adjusted individually and manually, using the
Level Detector simplifies this process (see
1. Use an external analog native-sized continuous grayscale test pattern with at least 256-levels.
2. Turn "Level Detector" ON.
3. Set "Level Value" to ~200. The image should now be black-and-white (or black-and-1 color, if you use
"Color Enable" function).
4. Adjust offset. Half of the pixels will move, the other half will not.
