Characteristic Specifications Supplemental Information
APx517 B Series Acoustic Analyzer: Specifications 41
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
Amplitude Range 0 to 25.456 Vpp
Amplitude Accuracy ±0.06 dB [±0.70%]
Residual IMD {notes 1,2,3} ≤ 0.010% [-80 dB]
Multi-tone, Wave File Playback
Sample Rate Range (SR) 8 kS/s to 108 kS/s, and
175 kS/s to 192 kS/s
Operation from 109 kS/s to 175 kS/s is
possible, but with degraded flatness
Maximum File Size 256 Msample
Amplitude Range 0 to 25.456 Vpp ".Wav" file must peak at digital full scale
to obtain selected amplitude
Flatness (1 kHz ref)
SR = 175 kS/s to 192 kS/sec Typically < 0.012 dB to 20 kHz
SR = 8 kS/s to 108 kS/s Typically < 0.04 dB to 20 kHz;
max frequency limited to ≈ 0.45 * SR
Spurious Content Typically < -110 dB 20 Hz to 20 kHz
Output Equalization
Arbitrary 30-pole output filter
