Ifft?

What exactly does the ifft function display.  For instance, if I measure an actual device and get its S2P file from a network analyzer, and them display the s2p file in genesys, what am I looking at when I ask for ifft(S[1,1]).

Is it the impulse response?  It does not look like a step response.  

I am trying to make S parameter measurements on a network analyzer, and do a Time Domain Reflectometer transformation with the measured data in Genesys.  It is kind of working, but strangely.

Thanks all.
