17-6 E5500 Phase Noise Measurement System Version A.02.00
The graph shown in Figure 17-4
of the reference source approaches the noise level of the UUT, the
level measured by the software (which is the sum of all sources
affecting the test system) is increased above the actual noise level of
the UUT.
