Video capabilities
To characterize the differential phase and differential gain a CCIR330 video line is used.
The video line contains five (flat) levels of luminance onto which the chrominance signal is
superimposed. The luminance gives various amplitudes which define the saturation of the
signal. The chrominance gives various phases which define the color of the signal.
Differential phase (or differential gain) distortion is present if a signal chrominance phase
(gain) is affected by the luminance level. The differential phase and gain represent the ability
to uniformly process the high frequency information at all luminance levels.
When a differential gain is present, color saturation is not correctly reproduced.
The input generator is the Rhode & Schwarz CCVS. The output measurement is done by
the Rhode and Schwarz VSA.
