Description
Purity pattern
Purity offers eight different full field patterns:
Black, White (100% Y)
Primary colors: Red, Green, Blue
Complementary colors: Magenta, Yellow, Cyan
P01: White
P02: Blue
P03: Red
P04: Magenta
P05: Green
P06: Cyan
P07: Yellow
P08: Black

The red and green patterns are most frequently used for checking
color purity. The red pattern is selected only this color should be visible; the presence of any other color is an indication that color purity
needs adjustment.
The green pattern provides a purity check for three in-line tubes. In the
in-line tubes, the guns are in a horizontal position and the green gun is
located in the center.
The blue is the complementary colors are often used to check the
color performance.
The red are used to ensure that there is no interference between the
sound and chroma carrier. Furthermore the red pattern is used to adjust the longplay delay level to minimum flicker.
In addition to the primary and complementary colors 100% white can
be selected as well as black pattern with color burst to check.

Gradual pattern
Gradual transition of colors.
P09: Red
P10: Green
P11: Blue
P12: Gray
Application
This pattern is for brightness control and luminance writing current. And this
can overall the color performance, amplitude response/resolution and
linearity of chroma amplitude.
P13
Color Bar
Comprises 8 vertical bars- White, Yellow, Cyan,
Green, Magenta, Red, Blue and Black
Application
The white bar, to adjust the amplitude of the color difference signals with
respect to the luminance signal on the picture tube. The blue and green
guns can be switched off to allow the amplitude of the R-Y signal to be adjusted. This is done by ensuring that no difference in brightness is observed
between vertical bars five and six of the color bar and the horizontal reference bar. In a similar fashion, the amplitude of the B-Y demodulator can
be determined.
P14
Grayscale
Full screen linear staircase signal with 8/16/32/64
identical steps from black to white
P15
P16
P17
P14: 8 steps
P15: 16 steps
P16: 32 steps
P17: 64 steps
Application
This is used to locate faulty linearity of the video amplifier or greyscale setting. Nonlinearities mainly result in a compression of the white level.

P18
Black-White Vertical
Full screen linear vertical bar signal with black/white
intervals of 1/6/12 pixels.
P19
P20
P18: 1 pixel
P19: 6 pixels
P20: 12 pixels
Application
This pattern serves for a quick check of color monitor’s horizontal bandwidth and phase behavior of a video transmission. Also, verify video amplifier and color temperature.
P21
Black-White Horizontal
Full screen linear Horizontal bar signal with black/
white intervals of 1/3/6 pixels.
P22
P23
P21: 1 pixel
P22: 3 pixels
P23: 6 pixels
Application
This pattern serves for a quick check of color monitor’s vertical bandwidth
and phase behavior of a video transmission. Also, verify video amplifier and
color temperature.

Application
This pattern is mainly used for checking and aligning dynamic and corner
convergence of TVs or monitors.
Running H
P30
Full screen filled with lines of H characters, a new
line of H will run from upper left corner and fill down
when a line is completed.
Application
This is the special test for test/video motion verification and refreshing rate.
Circle
P31
Black circles on white background, 640x480 has 4 by
3 total 12 circles, 800x600 has 5 by 3 total 15 circles,
1024x768 has 6 by 4 total 24 circles,
Application
It’s suited for checking the overall linearity and geometry of the screen of a
monitor or TV.
Black/White Up/Down
P32
Full screen filled with upper half of 100% white and
lower half of 100% black.
Application
This pattern is for brightness control and purity checking. Also, to do the
white setting and synchronization.

P34: This pattern serves for a quick check of color monitor.
P35,P36: This pattern can be used to check the video handling capabilities
of most parts of a television system.
