Dear ADS users,
I'm a new user of ADS and am trying to minimize the mutual coupling between coils in a multi-channel system using the S-parameters.
I created in ADS a differential generic port with the command "SnP_Diff component" with 3 terminals, where the 1rst terminal is a decoupling capacitor
and the other 2 terminals refers to my 2 indipendent input. The goal of my optimization is to find the value of the capacitor that minimizes the
mutual induction or the S(2,3) (or S(3,2)) at a specific frequency.
I have uploaded the S-matrix related to the equivalent my circuit in .CTI format, and I checked that the 3x3 matrix is present in the file correctly.
Now, after setting the OPTIMIZATION, the GOAL and the VARIABLES, ADS tells me that the matrix components available in the S-Matrix are just 1,2.
It is like it does not see the 3rd row&columns.
Is there any error in my generic procedure, or am I missing some knowledge about the S-matrix or ADS option?
Thank you so much,
Antonino M. Cassara'
p.s. I was doing the same procedure previously different time and was working, just I was having always to optimize with respect the S(1,1).

There might just be an issue with the syntax of the .s3p file you are using. I would suggest to use a regular ADS S3P component to read the citi .s3p file to see if it returns the same error. If it does then most likely there is a syntax/format issue with the .s3p file.
