Hi,
I am doing S parameter simulations of differential pairs in
connectors and PCBs. I have done single ended simulations on a 4 port
device and I have also converted the results to 2, mixed mode ports,
to look at the results in differential mode.
Of course, the connectors that I am using are large and have many
differential pairs. It occured to me that if I were to look at
crosstalk between the pairs, I would need a very large S parameter
matrix to do so. In addition, I am not sure that I would know how to
create such a mixed mode matrix.
So, is it better to look at crosstalk between the indivitual single
ended ports, or somehow create a matrix to look at the crosstalk
differentially. I have read the Agilent papers on "Balanced Device
Characterization" but they only work with simple 4 port devices.
Thank You
Tom
