Generator Variable Parameters
Clock Rate Range
All Inputs and Outputs 30 kHz to 52 kHz
Clock Rate Accuracy
The primary clock rates (32, 44.1, and 48 kHz) are
synthesized exactly, so accuracy depends solely
on the accuracy of the reference used (internal or
external).
Internal Ref Accuracy
10 ppm
Static Phase Difference
This is the phase difference between the generator
output and the selected reference (input or output).
The primary function of the measurement is to
check compliance with AES11-1991, section 5.3.
