If the output amplitude of your DUT is not sufficient to provide an adequate
measurement noise floor, it will be necessary to insert a low-noise amplifier
between the DUT and the test set. Refer to "Inserting an Device" in
"Absolute Measurement Fundamentals for details on determining the effect
the amplifiers noise will have on the measured noise floor.
VCO reference
In order for the noise measurement results to accurately represent the noise of
the DUT, the noise level of the reference source should be below the expected
noise level of the DUT.
