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 Vrms)
Measurement accuracy: < ± (2% of reading + resolution) for 100 Hz to 8 KHz,
< ±(3% of reading + resolution) for > 8 to 10 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
Typical external input impedance: 100 k ohms in parallel with 105 pF
Measurement resolution: 0.3% of expected level setting or 0.2 mV, whichever is greater

SINAD measurement
Types of signals measured: Sinusoidal audio signals
Measurement frequency range: 100 Hz to 10 kHz
AUDIO IN level range: 42.4 mV to 20 V peak (30 mV to 14.1 V rms)
Measurement accuracy: < ±1.0 dB for SINAD < 44 dB
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, minimum, maximum, average,
and standard deviation results
Concurrency capabilities: SINAD measurements can be made concurrently with all
analog and audio measurements
Measurement resolution: 0.01 dB
