Sweep segments
When the system begins measuring noise, it places the noise graph on its
display. As you watch the graph, you 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.
Congratulations
You have completed a phase noise measurement. This measurement of the test
set's low noise amplifier 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
that your system is operating normally.
