5. Adjust until the two transition regions overlap. The stripe of noise will be minimized, defined by the value
in the slidebar.
6. Set "Level Value" to ~800. The image should now be black-and-white.
7. Repeat Steps 4 and 5, but adjusting gain.
8. Repeat Steps 3-7 for all remaining colors. Your RGB source should now be OK.
There are 2 sets of values which are automatically saved with these controls. One value for Input #1, and one
for Input #2 (analog). The current set of values depends on which source is in use. This enables a source to be
processed correctly via 2 different inputs.
NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 represents no change in
normal odd pixel offset or gain. 3) Odd Pixel Adjustment eliminates "1 pixel on, 1 pixel off" patterns
only, not any type of larger patterns.

Peak Detector
The Peak Detector is fast method of defining individual input levels, and can improve the accuracy of input
levels set by the Auto Input level function. Enabling the Peak Detector activates a special operating mode for
detecting only pixels that are considered black or white-all other levels are displayed as a mid-level gray. When
used with a 16-step grayscale pattern in which the two black and white bands are known to be at opposite
edges of the image, you can watch these isolated areas while adjusting individual blacklevels and input drives
until both bands are just visible. Images from this source then display blacks and whites correctly without
crushing or washing out.
NOTE: If using Peak Detector with PIP, both images must have the same color space.
