Note: Frequency offset is not available when Through Mode (IQS-8510B only) is
selected.

Frequency Offset (ppm): Available with FC 1x/2x/4x/10x, and 10 Gig-E
interfaces only. Allows entering a positive or a negative frequency
offset in ppm. The default setting is 0.

Actual Frequency (bps): Available with FC 1x/2x/4x/10x, and 10 Gig-E
interfaces only. 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.
Interface Frequency Offset a
a. 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.
