PNA Residual Error Values

I want to measure the calibration residual error values for the PNA for directivity, source match and reflection tracking for a calibration done with ECal.  I have purchased Dr. Joel Dunsmore's book and in the section 3.9.2 he goes over how to derive residual error values by attaching loads and shorts on the end of an air-line.  On page 181 in that section, though, he states that you cannot use this method when using the ECal as it is a database calibration.  In the next paragraph he states that time-domain gating can be used instead of this method and my question is "can I use time-domain gating to derive the calibration residual error values with an ECal calibration"?
