Measuring Phase Noise
The following example shows a basic measurement of a 1 GHz carrier’s 100 kHz phase noise using markers:
1.Preset the analyzer using the Preset button.
2.On the analyzer, set up the following: Center Frequency: 1 GHz
Span: 1 MHz
RBW: 1 kHz
Sweep Time: 30 seconds
3.On the System Configuration menu, set the Optimize Phase Noise to Manual and set >85 kHz.
4.On the Trace Config menu, set the Trace 1 detector to Maximum.
5.Press the
6.On the Trace Config menu, select Trace 2 as the active trace, Trace Mode to
7.On the Marker menu, select Marker 2 as the active marker, set its Marker Function as a Delta Marker on Trace 2, and then set its frequency to 100 kHz.
8.On the Marker Config menu, set Marker 2 as a Noise Marker.
9.Read the delta marker value from the top of the graticule.
The display should look like the one in the figure below:
