Characterization Measurement Conditions
Picture Carrier Harmonics
No video signal
No audio signal
Measure in dBc, in reference to picture carrier (TVout_Ref), second and
third harmonic of channel frequency, resulting in the following spectrum
.
Out-of-Band Spurious
No video signal
No audio signal
Measure in dB
V 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
1GHz
):
In-Band Spurious
No video signal
No audio signal
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.
Video Bandwidth
No audio
Video: 600-mVp-p sinusoidal signal
inserted on the black level of active video
area
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.
Weighted Video Signal to Noise
Video: 100% white video signal, 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.
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.
