MC44BS373CA Data Sheet
Characterization Measurement Conditions
Picture-to-Sound Ratio
No video signal
No audio signal
PS bit set to 0 and 1
Measure in dBc sound carrier in reference to picture carrier (TVout_Ref)
for PS bit = 0 (PS = 12 dB typical) and for PS bit = 1 (PS = 16 dB),
Audio Modulation Depth—FM Modulation
Video black level
Audio signal: 1 kHz, 205 mVrms.
This is measured using a Rohde & Schwarz
AMFS demodulator in B/G and an
HP8903A audio analyzer at 1 kHz.
The audio signal, 205 mV at 1 kHz, is supplied by the audio analyzer, and
the FM demodulated signal deviation is indicated on the demodulator in
kHz peak.
This value is then converted into percentage of FM deviation, based on
specified standards.
Audio Frequency Response
Video black level
Audio signal: 50 Hz to 15 kHz, 100 mVrms
This is measured using a Rohde & Schwarz
AMFS demodulator in B/G and an
HP8903A audio analyzer.
The audio signal, 1 kHz 100 mVrms, is supplied by the audio analyzer,
and demodulated by the demodulator. The audio analyzer measures the
AC amplitude of this demodulated audio signal. This value is taken as a
reference (0 dB).
The audio signal is then swept from 50 Hz to 15 kHz and demodulated.
AC amplitude is measured in dB relative to the 1-kHz reference.
Audio pre-emphasis and de-emphasis circuits are engaged and all audio
analyzer filters are switched off.
Audio Distortion FM
Audio: 1 kHz, adjustable level
Video black level
This is measured using a Rohde & Schwarz
AMFS UHF demodulator in B/G and an
HP8903A audio analyzer at 1 kHz. The
output level of the audio analyzer is varied
to obtain a deviation of 50 kHz indicated on
the demodulator.
The input arms detector of the audio analyzer converts the AC level of the
combined signal + noise + distortion to DC. It then removes the
fundamental signal (1 kHz) after having measured the frequency. The
output rms detector converts the residual noise + distortion to DC. The
DC voltmeter measures both DC signals and calculates the ratio of the
two signals as a percentage.
Audio Signal to Noise
Audio: 1 kHz, adjustable level
Video: EBU color bars
This is measured using a Rohde & Schwarz
AMFS demodulator in B/G and an
HP8903A audio analyzer at 1 kHz. The
output level of the audio analyzer is varied
to obtain a modulation deviation of 25 kHz
indicated on the AMFS demodulator.
The audio analyzer alternately turns on and off its internal audio source
to make a measure of the audio signal plus noise and then another
measure of only the noise.
The measurement is made using the internal CCIR 468-2 filter of the
audio analyzer together with the internal 30±2-kHz (60 dB/decade)
low-pass filters.
The AMFS demodulator uses a quasi-parallel demodulation as is the
case in a normal TV set. In this mode the Nyquist filter is bypassed and
the video carrier is used without added delay to effectuate intercarrier
conversion. In this mode the phase noise information fully cancels out
and the true S/N can be measured.
