Abstract
A component color bars alignment test signal for calibrating a component picture monitor having as inputs a luminance component and two orthogonal chrominance components has a standard set of color bars and a contiguous chroma set of color bars. The chroma set of color bars is matched to the standard set so that a color that is sensitive to the adjustment of one of the chrominance components is adjacent to a color that is relatively insensitive to the adjustment of that one chrominance component. A gun of the component picture monitor is turned off and one chrominance component is adjusted until the appropriate pair of standard set and chroma set color bars are indistinguishable.
