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.

Picture Carrier Harmonics
Measure in dBc, in reference to picture carrier (TVout_Ref), second and
third harmonic of channel frequency, resulting in the following spectrum
Measure in dBµV spurious levels at 0.25, 0.5, 0.75 and 1.5 times channel
frequency, resulting in the following spectrum (measure from 40 MHz to
1 GHz
Measure in dBc, in reference to picture carrier (TVout_Ref), spurious
levels falling into video bandwidth starting from ±100 kHz from the picture
carrier up to ±5MHz.
The video signal is demodulated on the spectrum analyzer, and the peak
level of the 100-kHz signal is measured as a reference. The frequency is
then swept from 100 kHz to 5 MHz, and then the difference in dB from the
100-kHz reference level is measured.
The video analyzer measures the ratio between the amplitude of the
active area of the video signal (700 mV) and the noise level in Vrms on a
video black level which is shown below.
Video S/N is calculated as 20 x log(700/N) in dB.
