Typical Phase Noise Curve for an Agilent/HP 70420A Confidence Test
When the system begins measuring noise, it places the noise graph on its
display. As you watch the graph, you will see the system plot its
measurement results in frequency segments.
The system measures the noise level across its frequency offset range by
averaging the noise within smaller frequency segments. This technique
enables the system to optimize measurement speed while providing you with
the measurement resolution needed for most test applications.
You have completed a phase noise measurement. You will find that this
measurement of the Agilent/HP 70420A test set's internal noise source
provides a convenient way to verify that the system hardware and software
are properly configured for making noise measurements. If your graph looks
like that in
Figure
3-2, you now have confidence that your system is
operating normally.
