The firmware adds a second instance of the phase noise application which is
independent of the first one.
5.3 Result Evaluation
The phase noise application provides several tools to control the data displayed
in the various result displays. Some tools have an effect on the graphical result
displays, other on the numerical results and still others on both graphical and
numerical (for example in case the numerical results are based on the graphical
results).

5.3.1 Trace Smoothing
How to smooth the trace by averaging the measurement data
When you average the trace, the application measures the data several times
and builds an average over all measurements when it is done. Averaging mea-
surement data yields a smoother trace.
Trace averaging is applied to all traces.
1. Enter the "Overview" dialog box, and from there, enter the "Noise Config" dia-
log box.
2. Define the number of measurements to be performed in the "Sweep / Average
Count" input field, for example "10".
3. Start the measurement.
● In case of a single measurement, the application performs x measure-
ments over the frequency range you have defined. An average count of
"10", for example, would result in 10 measurements.
● In case of continuous measurements, the application performs a moving
average over the average count.
