I have a problem with the #channel #simulation.
I want to simulate a de-embeddet channel but I noticed that I get two different results although I simulate the same thing.
I use the same touchstone file for the snp2 and d#e-embedding building block (ChannelSim1.jpg) and get the following result (Result1.jpg).
However, if I simulate the new S-parameters first (ChannelSim22.jpg), save them into a new Touchstone file, and then simulate the channel (ChannelSim3.jpg), the result is different (Result2-jpg).
According to my understanding, the second result must be the right one.
But can someone explain where the difference is?
Is this a software bug?
Thank you in advance and best regards,
