Blue, as well as the complementary colors, are often used to check the color performance.
The other patterns (mainly RED) are used to ensure that there is no interference between the sound and chroma carrier. In
addition to the primary and complementary colors 100% white can be selected as well as black pattern with color burst. Purity
patterns are also used for measuring unwanted amplitude and phase modulation of the sub-carrier, AM and PM noise as it
occurs with VCRs.
Black/White Lines - The
vertical patterns provide a
quick way to check the color
monitor’s horizontal
bandwidth and phase
behavior. They help verify
video amplifier operation and the display’s color temperature. The horizontal pattern serves as a quick way to check of color
monitor’s vertical bandwidth and phase response. Like the vertical signals, they also are used to verify video amplifier
bandwidth and display color temperature.
When the output resolution is 1080i, the patterns 4, 5 and 6 are not supported.
Gradual - These signals check adjustment of the decoders,
especially the video de-emphasis decoders. In a monitor, the
chrominance signal should have the same amplitude in the
active video portion of the signal.
Grid - This pattern is mainly used for checking and aligning dynamic and corner convergence of TVs or monitors.
When the output resolution is 1080i 50/60, the Grid patterns are not supported.
HDCP - This pattern is used to test DVI and HDMI monitors with HDCP capability. All DVI and HDMI options,
including analyzer options are supported if the HDCP option is installed.
Others - The H pattern is mainly used for checking aligning
dynamic convergence and the Dot pattern is used for checking
and adjusting the static convergence. When using the Dot
pattern, the screen should contain pure white dots. The presence
of colored dots points to problems with focusing and convergence.
The Cross center is used to check and adjust the geometric distortion. The Cross center is ideal to center images on TV
monitors and to facilitate alignment of picture height/picture width. It is also used to check deflection linearity and pincushion
correction.
The Motion pattern is to check the correct digital video processing, especially Analog to Digital conversion. When Motion
pattern is On, the HDCP function will be turned Off. When the user switches to other patterns, the HDCP function will be
turned back On.
