[ Press 'DONE' ]
Note
If your display does not list the same six parameter types
shown in the menu above, you need to return to the
Type/Range menu and select the "Phase Noise using a
Phase Lock Loop" measurement before you proceed with
this demonstration.
When you set up your own signal source measurements, you
will need to enter the center (carrier) frequency of your
source-under-test. You will also need to enter the tuning
characteristics of the VCO source that you are using. (You
will find that Chapter 3 provides the tuning characteristics
for many Hewlett-Packard sources commonly used for this
measurement.)
2. Press the
