Video capabilities
To characterize the differential phase and differential gain, a CCIR330 video line is used.
The video line contains 5 (flat) levels of luma on which is superimposed chroma signal. The
first level contains no luma. The luma gives various amplitudes which define the saturation
of the signal. The chrominance gives various phases which define the color of the signal.
Differential phase (respectively differential gain) distortion is present if a signal chrominance
phase (gain) is affected by luminance level. They represent the ability to uniformly process
the high frequency information at all luminance levels.
When differential gain is present, color saturation is not correctly reproduced.
The input generator is the Rohde & Schwarz CCVS. The output measurement was done by
the Rohde and Schwarz VSA.
