Frequency
Note: Frequency offset is not available when Through mode is selected.
Frequency Offset (ppm): Allows entering a positive or a negative
frequency offset in ppm. The default setting is 0.
Actual Frequency (bps): Indicates the frequency (actual frequency +
Frequency offset) used for transmission.
Nominal Frequency (bps): Indicates the nominal frequency of the
signal.
On/Off button: Allows enabling the frequency offset generation. This
setting is disabled (Off) by default.

SONET/SDH Application
Interface
The frequency offset range is guaranteed for a source signal at 0 ppm offset. In the
event that the source signal already has an offset then, the output signal may
exhibit an offset larger than the range specified.
