Verify The Results - Agilent Technologies 8719D User Manual

Since the effect of the adapter has been removed, it is easy to verify the accuracy of the
technique by simply measuring the adapter itself. Because the adapter was used during the
creation of the two cal sets, and the technique removes its effects, measurement of the adapter
itself should show the S-parameters.
If unexpected phase variations are observed, this indicates that the electrical delay of the
adapter was not specified within a quarter wavelength over the frequency range of interest.
