Calibrating for Increased Measurement Accuracy
Adapter Removal Using ECal (ES Analyzers Only)
Figure 6-30 Calibrated Measurement
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
.
