TX Frequency
Note: The following TX Frequency information applies to serial interface only,
refer to TX Frequency on page 85 for parallel interface.

TX Frequency (GHz) indicates the frequency (actual frequency +
Frequency offset) used for transmission.

Offset (ppm) check box, when selected (cleared by default), allows to
set the frequency offset that will be generated. Use the “+” or “-”
button to respectively increment or decrement the frequency offset
value based on the defined Increment/Decrement Size, or directly
type the frequency offset value in the field. Possible offsets are:

Step Size (ppm) allows to set the increment/decrement value (from
0.1 to the maximum offset) that will be used when changing the
frequency offset with the “+” or “-” button.
Interface Frequency Offset
a
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.
