GSM analog audio distortion measurement
Types of signals
measured
Sinusoidal audio signals
Measurement frequency 100 Hz to 10 kHz
range
AUDIO IN level range 42.4 mV to 20 V peak (30 mV to 14.1 V rms)
Measurement accuracy < ± 12 percent of reading (± 1.0 dB) for
distortion > 0.67 percent
Residual THD plus noise < –60 dB or 200 μV rms, whichever is greater
Measurement trigger
source
Immediate
Measurement
synchronization
None required
Numerical result
Audio distortion
Multi-measurement
capabilities
1 to 999 measurements; average, minimum,
maximum, and standard deviation results
Concurrency capabilities GSM analog audio distortion measurements
cannot be made concurrently with GSM multi-
tone audio, but can be made concurrently with
all other measurements
Supplemental characteristics
Measurement resolution 0.1 percent
