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.
