I was thinking the same thing, brucek, but consider this:
For the sake of discussion, suppose that the receiver has some really goofy and exaggerated frequency response (FR). Do the calibration, and apply it in REW. Now do your sweeps and get everything perfect with REW and a BFD. Now, remove REW from the picture, and bring in a "perfect" spectrum analyzer, but that doesn't use a cal file (i.e., it's been calibrated on its own, and it flat from DC to infiinty at both input and output, etc.). If you remeasure, FR won't be flat due to the imperfectness of the receiver that was calibrated out with the REW cal file. That's what I'm thinking.
