Need Help on 5071C TDR Gated (Differential) S-Parameters

I'm making a 2-Port Differential TDR/S-Parameter measurement using the 5071C.  When I use the gating function and activate it, for example, on T11 (using gate coupling to link with S11), I can clearly see the effect on the S11 measurement.  However when I save and then compare the Touchstone data (S4P), I am getting the same exact results before and after gating.  Any help would be appreciated.
