Capabilities Description
Receiver Interface Parameter Measurements
Clock Rate
Range
All inputs: 30 kHz to 52 kHz
Accuracy
10 ppm
Input Equalization
The Main Input includes automatic line equalization
to measure and correct roll-off due to typical 110 Ω
digital audio cable.
Range
Accuracy
0 to 20 dB loss at 10 MHz
2 dB
Static Phase Difference
This is the phase difference between the selected
main input and the reference input. The primary
function of the measurement is to check
compliance with AES11-1991; section 5.3.
Range
Accuracy
+49.6% to –50.0% of the digital audio frame
1% of the digital audio frame
Eye Diagram
This is the data source for the eye diagram display
and its accompanying peak-to-peak jitter measure-
ment. It is the equivalent-time sample points of the
selected main input.
Time-base PLL Bandwidth
Bandwidth Accuracy
Amplitude Accuracy
120 Hz or 1.2 kHz, user selectable
10%
10% with calibration, 20% with factory calibra-
tion factors
Eye Diagram Residual Jitter 0.03 UI (combined residual jitter of reference
generator and main receiver, with 120 Hz time-
base bandwidth)
