Characterization Measurement Conditions
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.
