coefficients and overwrite the current active calibration set in use.

This process uses up an internal memory register. The calibration in this register is not the calibration created by adapter removal, rather it is a “scratch” calibration. You may wish to delete the register, or re-save the new calibration in this register as shown in the following step.

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 cal sets, and the technique removes its effects, measurement of the adapter itself should show the S-parameters.
