K parameter.

Display name: KT^2 (T Sweep)
Units: cycles per second per second (c/s^2)
The K (T Sweep) parameter sets the change in temporal frequency over time. If

K is initially 0.0, setting K

seconds, 20.0 after twenty seconds, and so forth. The temporal frequency will
increase to maximum, return to 0.0, and repeat the cycle as long as the value of
K remains greater than zero.

Y/G/X parameter. This parameter displays one of the three signal components: the
Y component for a YC
b
structure, or the X component for an XYZ sample structure. Use the left (◄) or
right (►) arrow button to set the component to ON or OFF.
Cb/B/Y parameter. This parameter displays one of the three signal components:
the C component for a YC
b
sample structure, or the Y component for an XYZ sample structure. Use the left
(◄) or right (►) arrow button to set the component to ON or OFF.
Cr/R/Z parameter. This parameter displays one of the three signal components:
the C component for a YC
r
sample structure, or the Z component for an XYZ sample structure. Use the left
(◄) or right (►) arrow button to set the component to ON or OFF.
NOTE.
When the sampling structure for the current format uses the YCbCr color
space, the default settings enable only the Y channel. This results in the familiar
black to white zone plate patterns. When the RGB color space is used the default
settings enable all three channels, also resulting in the black to white zone plate
patterns. A colored zone plate pattern can be created by enabling or disabling
individual channels. When the XYZ color space is used, the resultant patterns will
show some chroma in all combinations of the X/Y/Z channel settings, due to the
inherent encoding of this color space.
