Phase Matching

Many thanks to any individual who can help me with the following question.... 

How do you conduct and test for a Phase Matching Cable (50 Ohm)

Below is a description for testing... Does my Network Analyzer have the capabilities to test for the following specifications?  Model E5071B

I have determined that the original length of the RG393 (70% VF) was ~13.44-13.5-wavelengths at 2.54 GHz.  The electrical equivalent for LMR-600UF (87% VF) at 13.44-13.5 wavelengths would be ~54.375 to 54.6" pin to pin.  As I indicated the transmission line will need to handle 400 watts rms at 2.54 GHz, otherwise I'm afraid I'll have a meltdown.  The cable extra length required to compensate for the higher VF will also help in routing the cable between the power supply and series section tuner. 

Thanks in advance for any assistance.

P.S.  We normally conduct cable sweeps between the frequency ranges 300 KHz to 8.5 GHz, providing RL, IL, VSWR, etc.... The above description was a bit far from normal.
