VCO Reference Source
This setup calls for a second signal source that is a similar type to that of the
UUT. The second source is used as the reference source. In order for the
noise measurement results to accurately represent the noise of the UUT, the
noise level of the reference source should be below the expected noise level
of the UUT. (For additional help in selecting an appropriate reference
source, refer to
Chapter 6, "Selecting a

Confirm your connections as shown in the connect diagram. At this time
connect your UUT and reference sources to the test set. The input
attenuator (Option 001 only) has now been correctly configured based
on your measurement definition.
