Fixture De-Embedding

We have module fixtures that use multiple 0.047 diameter cables.  The cables have an SMA on one end and a GPPO on the other.  I would like to use de-embedding to remove the cables as they are very lossy.  I would like to use the one-port characterization in the “Handbook of Microwave Component Measurements” in section 9.3.1 but it seems to require two calibrations, and we don’t have a GPPO calibration kit.  Can you recommend this or another characterization method?  The time-domain method (Section 9.5) seems difficult for us to use as the GPPO connectors are mounted to the fixture.
