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.
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?
