The primary version has 16 full-height vertical color
bars. The order of the bars is shown below. The
secondary version splits the field into a top and
bottom half. The bars in the bottom half of the
screen are in reverse order.
When digital video is being output, 33% Gray
changes to 50% Gray and 67% Gray becomes either
Black or some gray level depending on how the
display interprets the video information.
Verify that all video channels is functional
To verify that none of the video channels are bad
or hooked up incorrectly
Compare the sequence of color bars with the table.
Missing bars may indicate a dead or unconnected
channel. The transition between the bars should
be sharp and distinct. Each bar also should be
uniform in color and intensity across its entire
width. Non-uniformity may indicate problems with
the response of the video amplifiers. If all the bars
are present but in the wrong order, one or more
inputs may be swapped.
