Signal
Note: Frequency offset is not available when Through mode is selected.
Step Size (ppm) allows setting the increment/decrement value (from
0.1 to the maximum offset) that will be used when changing the
frequency offset with the “+” or “-” button.
RX Frequency
Note: The following RX Frequency information applies to serial interface only,
refer to RX Frequency on page 107 for parallel interfaces.
Frequency (GHz) indicates the frequency of the input signal.
Offset (ppm) indicates the frequency offset between the standard rate
specification and the rate at the input signal.

a. The frequency offset range is guaranteed for a source signal at 0 ppm. In the event
that the source signal already has an offset, then the output signal may exhibit an
offset larger than the range specified.
