Trace smoothing is applied immediately after you have applied it to a trace.
For more information on how this is done, refer to the R&S
FSPN user man-
ual.
How to remove spurs from a trace
By default, the application already shows a trace without spurs (the yellow one).
However, you can decide for each trace individually whether it shows spurs or
not.
Spur removal is done after traces have been smoothed in any way.
1. Enter the "Overview" dialog box, and from there, enter the "Analysis" dialog
box.
2. Select the vertical "Trace" tab, and then the horizontal "Traces" tab.
3. For any trace, remove or display spurs individually. You can also enter a
threshold that defines a level from which a spur is recognized as a spur.
The application removes all signals that are above the threshold from the
trace spur removal is applied to. Signals with levels below the threshold are
not regarded as spurs and are still displayed.
For more information about spur removal, refer to the R&S
FSPN user man-
ual.
Note:
Note that the threshold is always taken into account in the spur table,
regardless of whether spur removal is on or off.

Integration Ranges
How to define integration ranges
For the integrated measurements (residual AM, FM and PM and jitter), you can
define custom integration ranges.
By default, the integration range corresponds to the measurement range defined
by the frequency offsets. Custom integration ranges can have any range you
desire.
