Interface
TX Frequency
Note: The following TX Frequency information applies to serial interface only,
refer to TX Frequency on page 105 for parallel interfaces. Not available
when using an active copper SFP.
TX Frequency (GHz) indicates the frequency (actual frequency +
Frequency offset) used for transmission.
Offset (ppm) check box, when selected (cleared by default), allows
setting the frequency offset that will be generated: ±120 ppm for all
Ethernet rates at the exception of 10GE WAN which is ±50 ppm; not
supported for 10M electrical. 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.
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.
