Characteristic Specifications Supplemental Information
APx517 B Series Acoustic Analyzer: Specifications 37
Non-Harmonic Content Typically < -100 dB, 20 Hz to 20 kHz
DC Offset Range ±3.00 Vdc unbalanced DC offset limits maximum ac signal
Residual DC Offset +/-5 mV typically < 650 uV
Noise Characteristics
Shape White or Pink (5 Hz to 86.4 kHz),
IEC 60268-1, or BS EN 50332-1
Amplitude Range 0 to 48.08 Vpp Amplitude calibration is approximate
Residual Noise {Note 2}
20 Hz to 20 kHz BW 30 uVrms [-88.8 dBu]
IMD Test Signals
SMPTE & MOD
Lower Frequency (LF) 40 Hz to 1.00 kHz LF tone must be 1/6 * HF tone
SMPTE Upper Frequency
(HF)
2.00 kHz to 60.00 kHz
MOD Upper Frequency (HF) 240 Hz to 60.00 kHz
Mix Ratio (LF:HF) 10:1, 4:1, or 1:1
Amplitude Range 0 to 48.08 Vpp
Amplitude Accuracy ±0.06 dB [±0.70%]
Residual IMD {notes 1,2,3} 0.020% [-74 dB], 4:1 mix ratio
DFD & CCIF
Difference Frequency (Fdiff) 80 Hz to 2.00 kHz Fdiff = |F2 - F1|
Fmean must be 6*Fdiff
Mean Frequency (Fmean) 250 Hz to 60.00 kHz Fmean = (F1 + F2)/2
