Table 38: AES audio inputs (Option AD)
Characteristic Performance requirement Reference information
Inputs 2 sets with 8 Channels each, 32, 44.1, 48,
and 96 kHz, 24-bit, Meets Requirements
of AES 3-ID and SMPTE 276M-1995.
Input Connector BNC, terminated, unbalanced.
Input Impedance 75 Ω
Return loss, typical Typically better than 30 dB to 12 MHz.
Input A has Passive terms that are
the same with power on or off. Input
B has active terms that go to a higher
impedance with the power off.
Input Amplitude Range (typical)
0.2 V to 2 V
p-p.
Input Sample rate 32k, 44.1k, 48k, and 96k samples/second
Input Lock Range (typical) Greater than ± 5% of nominal sample
rate. After exceeding 5%, the instrument
may search again for a new lock point.
Typically stays locked to 12.5%.
Level Meter Accuracy over Frequency
(typical) 0.2 dB from 20 Hz to 20 kHz 0 to
–40 dBFS sine wave, peak Ballistic mode.
Audio Levels Bars display signals up to 0 dBFS.
