perform multiple ratioed measurements

Using a 5224 4-port pna-x.

We would like to do relative amplitude/phase receiver measurements using the 4 measurement receivers. We would use an external source to provide power to the DUT. Then the measurement would use one receiver, probably A, as the reference, to give three ratioed measurements, B/A, C/A, and D/A. And we would also like to get an absolute power then from A. The help seems to indicate that this can be done. Our measurement is actually frequency translated, but we are only interested in outputs that are at a single CW frequency.

So the question is, first, can this be done. Assuming this can be done, how is the calibration done. I've tried some calibrations, but none of them seem to be recognized by the measurements.We are using an ECAL.
