Adapter Removal Using ECal (ES Analyzers Only)
Verify the Results
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 calibration 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. To correct this, recall both cal sets; since the data was previously stored to disk,
change the adapter delay, and press .
