Frequency
Fixed/Sweep allows selecting the frequency generation method. Only
available with Ethernet interfaces when the Offset check box is
cleared. Not available with FlexE BERT.

Fixed (default): uses a fixed offset frequency value for generation.

Sweep : increases and decreases repetitively the frequency to
cover the defined frequency offset range using a 1 ppm step at an
average rate of up to 10 ppm/sec. Starting at offset 0 the min value
is reached then repetitively increases to the maximum value then
decreases to minimum value.
Step Size (ppm) , available with Fixed frequency, allows setting the
increment/decrement value (from 0.1 to either 50 or 120 depending on
the test configuration) that will be used when changing the frequency
offset with the “+” or “-” button.
Range , available with sweep frequency, allows setting the range for
frequency sweep generation.
Interface Frequency Offset
a
a. The frequency offset range is guaranteed for a source signal at 0 ppm. In the event
that the source signal already has an offset, then the output signal may exhibit an
offset larger than the range specified.
