Signal (Transport)
TX Frequency
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:
Note: Frequency offset is not available when Through mode is selected.
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.
