Signal set Signals in the signal set Description
B-Y Valid Ramp
R-Y Valid Ramp
range testing in all color spaces. These three ramps are also
available as individual patterns that span the picture width. First,
the Y Valid Ramp spans from Black to white, across the valid
range of the luminance (Y) channel. Next, the B−Y Valid Ramp
spans from yellow to cyan, across the valid range of the Cb color
difference channel. Last, the R−Y Valid Ramp spans from cyan to
red, across the valid range of the Cr color difference channel.
3 Channel Ramp Wide ramp from the lower valid value to the upper valid value for all
three channels. This pattern is color-independent, so it will appear
differently in YCbCr, RGB, or XYZ color spaces. On each side of the
ramp there are small plateaus at the blanking level (Black) and at the
valid level.
Limit Ramp Wide ramp that spans the legal limit range (4–1019 for 10-bit formats
and 16–4079 for 12-bit formats) for all three channels. On each side
of the ramp there are small plateaus at the blanking level, the valid
level, and the limit level.
Shallow Ramp Matrix Vertical matrix of shallow ramps that together span the range
between legal limits (4–1019 for 10-bit formats and 16–4079 for 12-
bit formats). Each bit value is held for 16 pixels for 10-bit formats and
for 4 pixels for 12-bit formats. There is overlap between the end of
one ramp and the start of the next ramp.
Color Ramp Matrix Vertical matrix of ramps across the colors available in the valid RGB
gamut. Each set of ramps transitions between adjacent hues: red–
yellow–green–cyan–magenta–blue–red. From the top of the pattern,
the first three rows of ramps are at 25%, 50%, and 75% saturation.
The fourth row of ramps includes fully saturated colors at 100%
value. The next three rows of ramps are at 75%, 50%, and 25%
value. The bottom row of ramps is monochrome.
Flat Field 0% Flat Field (Black)
50% Flat Field
100% Flat Field (White) Full-frame monochrome flat fields. The factory installed patterns
include 0% (Black), 50%, and 100% (white).
You can install extended signal sets, which include additional
patterns for the remaining 10% increments. (See Table 39.)
100% Red Field, 100% Green Field,
100% Blue Field, 100% Cyan Field,
100% Magenta Field, 100% Yellow Field Full-frame color flat fields. The factory installed patterns include
each of six colors (red, green, blue, cyan, magenta, and yellow) at
100% value.
You can install enhanced signal sets, which include additional
patterns for these six colors at 75% value. (See Table 39.)
10% Flat Field, 20% Flat Field,
30% Flat Field, 40% Flat Field,
60% Flat Field, 70% Flat Field,
80% Flat Field, 90% Flat Field
Full-frame monochrome flat fields available in individual patterns
from 10% to 90% in 10% increments.
These signals are not part of the factory installed signal sets. You
must install the enhanced signal sets to access these signals. (See
Table 39.)
75% Red Field, 75% Green Field,
75% Blue Field, 75% Cyan Field,
75% Magenta Field, 75% Yellow Field Full-frame color flat fields available in individual patterns of 75%
value for each of six colors (red, green, blue, cyan, magenta, and
yellow).
These signals are not part of the factory installed signal sets. You
must install the enhanced signal sets to access these signals. (See
Table 39.)
Black to White-1, Black to White-2,
Black to White-3, Black to White-4,
Black to White-5, Black to White-6, Full-frame monochrome flat fields representing the individual steps
in the SMPTE EG 432–1 step-scale patterns available under the
MONITOR button.
These signals are not part of the factory installed signal sets. You
