APx515 B Series Audio Analyzer: Analog I/O Specifications 47
515
Amplitude Accuracy ±0.06 dB [±0.70%]
Residual IMD
1,2,3
0.0010% [–100 dB]
Multitone, Wave File Playback (requires option HST)
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 32 MSample.
Amplitude Range 0 to 45.2 Vpp, balanced;
0 to 22.6 Vpp, unbalanced.
.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 <–100 dB
Output Equalization
Arbitrary 30-pole output filter
Source Resistance (Rs)
Balanced Selectable 100 ±1% or 600 ±1%. Grounded, symmetrical
Unbalanced Selectable 50 ±1.5% or 600 ±1%. Electronically floating, 0.3 Vpk max;
bnc shield to ground ≈10-17 || 22nF
Common Mode Test Same as Balanced selections
