Interface
TX Frequency
Note: The following TX Frequency information applies to serial interface only,
refer to TX Frequency on page 214 for parallel interfaces. Not available
when using an active copper SFP.
TX Frequency (GHz) indicates the frequency (actual frequency +
Frequency offset) used for transmission.
Note: Frequency offset is not available with OBSAI, CPRI in RRH emulation mode,
RFC 6349 test application.
Offset (ppm) check box, when selected (cleared by default), allows
setting the frequency offset that will be generated: ±120 ppm for all
Sync, Fibre Channel, and 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.
