5061B ENA Enhanced Responce VS 1 Port + Thru

I am trying to figure out what the differences between doing and "Enhanced Responce" calibration VS "1 Port" + "Thru" calibration methods. We have recently upgraded some of our old 871X analyzers to the ENA models and we are learning what is the best method to calibrate. The Enhanced Responce seems to be the same as combining a 1 port and a thru calibration, but the Q reading of the filter when at low level is different between the two calibrations. The analyzer is setup with the S11 and S21 being the appropriate ports that need to be calibrated.
