No audio signal
Video: a 700-mVp-p, 100-kHz sinusoidal
signal is inserted on the black level of active
video area.This is generated using a
Rohde & Schwarz video generator SAF
and inserting the required frequency from
an RF signal generator.

Sound Subcarrier Harmonics
TVOUT Output Attenuation
Measure in dBc picture carrier at ATT = 1 with reference to picture carrier
at ATT = 0
Measure in dBc second and third sound harmonics levels in reference to
picture carrier (TVout_Ref).
Measure in dBc, in reference to picture carrier (TVout_Ref), second
harmonic of chroma at channel frequency plus two times chroma
frequency, resulting in the following spectrum.
Measure in dBc, in reference to picture carrier (TVout_Ref),
intermodulation product at channel frequency plus the sound carrier
frequency (+5.5 MHz) minus the chroma frequency (–4.43 MHz),
resulting in the following spectrum (Intermodulation product is at the
channel frequency +1.07 MHz):
