•
A user-defined Step Size can be set (in PPM's), and a
user-defined Step Duration (in Seconds) can also be
configured.
The min/max frequency offset range is -150.0 to 150.0 for
Packet based mappings.
Use the keypad to enter the offset frequency parameters.
The Line Frequency Offset setting is only available when
the Clock Reference is set to Internal timing.
Sets the Optical Channel Payload Unit (OPU) frequency
offset in ppm.
The OPU Frequency Offset setting is only available for
