Video: 100% White video signal — 1 Vpk-pk.
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.
Same as above with CCIR filter disabled.

Unweighted Video Signal to Noise
Weighted Video Signal to Noise
Measure in dBc, in reference to picture carrier (RFOUT), 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 1.0 GHz
Measure in dBc, in reference to picture carrier (RFOUT), spurious levels falling
into video bandwidth Fo ± 4.2 MHz (15.125 KHz & 31.25 KHz from reference
dividers and 4 MHz from crystal).
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 4.2 MHz, and then the difference in dBc 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.
VideoS/N is calculated as 20 x log(700 /N) in dB.
Same as above.
