Measurement Configuration
The Phase Noise application provides several tools that make the measurement proc-
ess easier to handle or allow you to customize the measurement configuration accord-
ing to your needs.

How to define the measurement range
The measurement range defines the carrier frequency offset over which the phase
noise measurement takes place.
1. Enter the "Overview" dialog box, and from there, enter the "Noise Config" dialog
box.
2. Select the "Noise Config" tab.
3. Define the measurement range with the "Start Offset" and "Stop Offset" properties.
The application adjusts the measurement range. You can see this change, for
example, in the noise diagram result display.
Note
: In case of baseband measurements, the measurement range is defined by
an absolute start and stop frequency instead of offsets.

How to search for signals
The application allows you to search for a carrier signal, instead of defining the carrier
frequency manually.
1. Enter the "Overview" dialog box, and from there, enter the "Frequency" dialog box.
2. Turn on the "Auto Search" feature (it is on by default).
3. Define the frequency range in which the search should take place ("Start" and
"Stop"). By default the search is done in the maximum frequency range supported
by the hardware.
4. Define a "Threshold" for the search. Signals below the threshold are ignored during
the search.
When the application finds a signal with appropriate characteristics, it starts a
phase noise measurement in the
