Characterization Measurement Conditions
Characterization Measurement Conditions
Same as above with CCIR filter disabled
Video: 5-step grey scale, 1 Vp-p
No audio signal
This is measured using a Rohde & Schwarz
AMFS UHF demodulator in B/G (using a
CCIR Rec. 567 weighting network),
100-kHz to 5-MHz band with sound trap
and envelope detection, and a Rohde &
Schwarz UAF video analyzer.

MC44BS373CA Data Sheet
Same as above
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 grey scale. 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 grey scale. The largest
positive or negative difference indicates the distortion.
The video analyzer method takes the worst step from the first 4 steps.
This is measured using an HP8596E spectrum analyzer with a TV trigger
option, allowing demodulation and triggering on any specified TV line.
The analyzer is centred on the maximum peak of the video signal and
reduced to 0 Hz span in linear mode to demodulate the video carrier
The modulation depth is calculated as (A – B) / A x 100 in percent.
Same measurement method for L standard, with inverted video.
