882 Video Test Instrument User Guide (Rev A.35) 281
The MnsPG Image is shown below. The example below shows an image that displays two
(2) of the eight (8) hue families (in this case Yellow and Green Yellow). There are a series
of these images (40 in total) that are accessible as sub images through the 882E front
panel. Each hue in the MnslCLR image set has 4 sub hues, labeled 2.5, 5, 7.5 and 10, that
represent a hue as it traverses around the perimeter of the diagram above and transitions
into the adjacent hues. Each such sub image depicts the chroma and value variances of
one of these sub hues. Each sub image provides a color block for each chroma and value
level for that sub hue. The value varies along the vertical axis and the chroma varies along
the horizontal axis.
Note: The image as shown in this User Guide is not representative of how it will actually
appear on an xvYCC display.
When examining this image on an xvYCC display the differences between adjacent colors
should be preceived to be the same. Note that this depends on how you have
implemented the feature. Typically if you see adjacent colors that look very similar or
strikingly different, then this indicates that the colors may not be represented properly on
the display.
To test an HDMI display for xvYCC:
1. Set up the 882 for HDMI output. See “ Setting up the 882 for HDMI testing ” on page 259.
2. Press the Source key and select the desired format.
Alternatively, you can load the format with the following command:
