PIN CIRCUIT SCHEMATICS
Figure 3. Pin Schematics
Audio Signal to Noise
Audio: 1.0 KHz, adjustable level
Video: EBU Color Bars
This is measured using a Demodulator in B/G
and an Audio Analyzer at 1.0 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 CCIR468-2 Filter of the Audio
Analyzer together with the internal 30+/-2.0 KHz (60 dB/decade) Lowpass 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.
