Video: 5 step Grey Scale — 1 V
No audio signal
This is measured using a Demodulator using
a CCIR Rec. 567 weighting network, 100 KHz
to 4.2 MHz band with sound trap, and
envelope detection, and a Video Analyzer.

On line CCIR 330, the video analyzer DP measure consists of calculating the
difference of the Chroma phase at the black level and the different chroma
subcarrier phase angles at each step of the greyscale. The largest positive or
negative difference indicates the distortion.
The video analyzer method takes the worst step from the first 4 steps.
On line CCIR 330 shown below, the video analyzer DG measure consists of
calculating the difference of the Chroma amplitude at the black level and the
different amplitudes at each step of the greyscale. The largest positive or
negative difference indicates the distortion.
The video analyzer method takes the worst step from the first 4 steps.
CCIR line 330 corresponds to FCC line 17 in NTSC/M standard.
This is measured using a HP8596E Spectrum Analyzer with a TV Trigger option,
allowing demodulation and triggering on any specified TV Line. The analyzer is
centered on the maximum peak of the Video signal and reduced to zero Hertz
span in Linear mode to demodulate the Video carrier.
The Modulation Depth is calculated as (A-B)/A x 100 in%.
