specification and the rate of the input signal.
Max (+) Offset (ppm) indicates the offset between the standard rate
specification and the largest rate recorded from the received signal.
Max (-) Offset (ppm) indicates the offset between the standard rate
specification and the smallest rate recorded from the received signal.
