Why 100 ohm & 25ohm are used in input ports in differential TDR simulation?

I am using ADS 2015. I have created a differential channel.Now I want to do TDR simulation. I googled and found schematic settings below.


Differential TDR simulation settings


In the settings after step in the input 100 ohm and 25 ohm are put and similar to the output ports as well. I want to know why is 100 ohm and 25 ohm are attached? why not 50 ohm & 50 ohm?


Is there any other way to do TDR simulation for differential channel except TDR frontpanel tool?
