MC44BS374T1/374T1A Advance Information

Chroma/Sound Intermodulation

No audio signal

Video: 700m Vpp 100 kHz 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 (+5,5 MHz) minus the chroma frequency (-4,43 MHz),

resulting in the following spectrum.

Intermodulation product is at the channel frequency +1,07 MHz.

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 dBuV spurious levels at 0.25, 0.5, 0.75 and 1.5 times

channel frequency, resulting in the following spectrum

Measure from 40MHz 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.
