Device and Signals Set-Up
Measurement Set-Up
Audio Modulation Index — FM Modulation
Video: Black Sync
Audio signal: 1.0 KHz, 205 mVrms.
This is measured using a Demodulator and
The audio signal 205 mV at 1.0 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 in% of FM deviation, based on specified standards.
an Audio Analyzer at 1.0 KHz.
Audio Frequency Response
Video: Black Sync
Audio signal: 50 Hz to 15 KHz, 100 mV rms
This is measured using a Demodulator and
an Audio Analyzer.
Audio: 1.0 KHz, adjustable level
Video: Black Sync
This is measured using a Demodulator and
an Audio Analyzer at 1.0 KHz. The output
level of the Audio analyzer is varied to obtain
a deviation of ±25 KHz indicated on the
Demodulator.
Audio: 1.0 KHz, adjustable level
Video: EBU Color Bars
This is measured using a Demodulator 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 signal 1.0 KHz 100 mV rms is supplied by the Audio Analyzer,
demodulated by the Demodulator and 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 1.0 KHz reference.
Audio pre-emphasis and de-emphasis circuits are engaged, all audio analyzer
filters are switched OFF.
Audio Distortion FM
The input rms detector of the Audio Analyzer converts the ac level of the
combined signal + noise + distortion to dc. It then removes the fundamental
signal (1.0 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 in% of the two signals.
ADist = ( Distorsion + Noise ) ? ( Distorsion + Noise + Signal )
Audio Signal to Noise
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.
ASN ( dB ) = 20 × log ( Signal + Noise ) ? ( Noise )
