Audio analyzer specifications
All specifications for the audio analyzer apply to signals present at
test set’s AUDIO IN ports.
Audio analyzer de-emphasis: 750 µs, de-emphasis settable as off
or on
Audio analyzer expander: settable as off or on with reference
level setting of 10 mV to 10 V
Audio analyzer filters: settable choices of none, C-message, 50 Hz
to 15 kHz band pass, 300 Hz to 15 kHz band pass, or 100 Hz
bandwidth tunable band pass tunable over 300 Hz to 15 kHz
Audio level measurement
Types of signals measured: sinusoidal audio signals
Measurement frequency range: 100 Hz to 15 kHz
AUDIO IN level range: 7.1 mV to 20 V peak (5 mV to 14.1 V rms)
Measurement accuracy: < ±(2% of reading + resolution) for
100 Hz to 8 kHz, < ±(3% of reading + resolution) for 8 to 15 kHz
Measurement THD plus noise: < 200 µV rms
Measurement detector: selectable choices of rms and peak
Measurement trigger source: immediate
Available result: audio level
Multi-measurement capabilities: 1 to 999 measurements,
average, minimum, maximum, and standard deviation results
Concurrency capabilities: audio level measurements can be made
concurrently with all other measurements
External input impedance: typically 100 k Ω in parallel with 105 pF
Measurement resolution: typically 0.3% of expected level setting
or 0.2 mV, whichever is greater
SINAD measurement

Residual THD plus noise: < −60 dB or 200 µV rms, whichever is
greater
Measurement trigger source: immediate
Available result: SINAD ratio
Multi-measurement capabilities: 1 to 999 measurements,
average, minimum, maximum, and standard deviation results
Concurrency capabilities: SINAD measurements can be made
concurrently with all analog and audio measurements
Measurement resolution: typically 0.01 dB
