Characterization Measurement Conditions
MC44BC373C/374C Technical Data
Second Harmonics of Chroma subcarrier
No audio
Video: a 700mVpk-pk 100Khz sinusoidal
signal is inserted on the black level of
active video area.
Measure in dBc, in reference to picture carrier (TVout_Ref), second
harmonic of chroma at channel frequency plus 2 times chroma
frequency, resulting in the following spectrum
Chroma/Sound intermodulation
No audio signal
Video: 700mVpk-pk 100Khz sinusoidal
signal 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
a RF Signal generator.
Measure in dBc, in reference to picture carrier (TVout_Ref),
intermodulation product at channel frequency plus the sound carrier
frequency (+5,5Mhz) minus the chroma frequency (-4,43Mhz), resulting
in the following spectrum.
Intermodulation product is at the channel frequency +1,07Mhz.
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.
