Selecting the trace for residual calculations
Residual calculations are only performed when you select an (active) trace that serves
as the data source (when the selected trace is inactive, residual effects are not calcula-
ted).
You can select any trace as the data source ("Trace 1" to "Trace 6" in the dropdown
menu), and define the
frequency range over which the integration is performed.
When you select "None" from the dropdown menu, residuals effects are not calculated.
Remote command:
CALCulate<n>[:RANGe<j>]:EVALuation:TRACe
on page 369
Defining the integration range
You can define up to 10 integration ranges on different traces .
By default, the R&S FSPN integrates over the entire frequency range defined for the
measurement (Range = "Meas"). You can, however, also define custom integration
ranges (Range = "Manual").
In that case, the input fields next to the "Range" control become available to define a
customized integration range. The application shows orange lines ("Range <x>") in the
graphical result display to indicate custom ranges.

Working with weighting filters
The weighting filter feature provides functionality to correct integrated measurements
and thus compensate for external effects that affect the results in certain frequency
ranges. A weighting filter is a useful feature if you already know that this is the case
and would like to compensate for these effects.
Note that the weighting filter only has an effect on the integrated measurement results
and has no effect in the noise diagram or other numerical results.
Applying weighting filters ← Working with weighting filters
When you apply a weighting filter, the R&S FSPN takes the correction values defined
in the weighting filter into account for the calculation of integrated measurements.
The "Weighting Filter" dropdown menu contains all weighting filters that are available
on the internal hard disk of the R&S
FSPN.
