TX Frequency
Note: The following TX Frequency information applies to serial interface only,
refer to TX Frequency on page 133 for parallel interface. Frequency offset is
not available when Through mode is selected.
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:
