Absolute Measurement Examples
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 input. (Refer to the section “Inserting a
Device" on page 122 for details on determining the effect that the amplifier’s
noise will have on the measured noise floor.)
Agilent 8663A VCO reference
This setup uses the 8663A as the VCO reference source. 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.
