MC44BC375U
Chroma/Sound Intermodulation
No audio signal
Video: 700 mV(pp) 100 kHz sinusoidal signal
inserted on the black level of active video
area.This is generated using a Video
Generator and inserting the required
frequency from a RF Signal generator.
Measure in dBc, in reference to picture carrier (RFout_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 (RFout_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 dB
V spurious levels at 0.25, 0.5, 0.75 and 1.5 times channel
frequency, resulting in the following spectrum.
Measure from 40 MHz to 1.0 GHz
.
In Band Spurious / 4 MHz Crystal Spurious
No video signal
No audio signal
Measure in dBc, in reference to picture carrier (RFout_Ref), spurious levels
falling into video bandwidth Fo+/-5.0 MHz (15.125 KHz & 31.25 KHz from
reference dividers and 4 MHz from crystal).
Video Bandwidth
No audio
Video: 600 mV(pp) sinusoidal signal inserted
on the black level of active video area.
The Video signal is demodulated on the spectrum analyzer, and the peak level
of the 100 KHz signal is measured as a reference. The frequency is then swept
from 100 KHz to 5.0 MHz, and then the difference in dBc from the 100 KHz
reference level is measured.
