S parameters

I am trying to understand how to use the S-parameters provided for the AD9680 converter.

 

The files that come in the zip file are:

ADCA50.s2p

ADCA100.s2p

ADCA200.s2p

ADCA400.s2p

ADCB50.s2p

ADCB100.s2p

ADCB200.s2p

ADCB400.s2p

 

I think I understand the file naming format as ADCXYYY.s2p where X is either channel A or B of the two channel converter, and YYY is the setting for the configurable input impedance.

 

What I don't understand is the fact that these are S2P files.  Are the two ports the positive and negative inputs of the differential input?  I couldn't find anywhere that specified what the two ports are.
