The table contains a list of spot noise values for selected frequency offsets (in
the default state, these are the decade edges) on each active trace.
For more information on the table contents see the R&S
FSWP user manual.
Tip:
You can define custom spot noise frequencies in the "Spot Noise" tab of
the "Noise Config" dialog box.
Measuring integrated noise
Integrated measurements show various noise characteristics, like the residual
noise, integrated over a certain offset frequency range.
► Open the SmartGrid ( ) and drag the "Integrated Measurements" item from
the evaluation bar into the display.
The table contains a list of integrated measurement results.
For more information on the table contents see the R&S
FSWP user manual.
Tip:
You can define
in the "Integration Ranges" tab
of the "Noise Config" dialog box.

The Additive Noise Measurement
Additive noise measurements require the signal source output that is available as
an optional hardware component.
Test setup
Connect the DUT via cable to the RF input and the signal source output of the
R&S
FSWP as shown in the illustration.
