i got the model from a supplier.
What I found quite interesting:
According to the header in the ASCII files it was a full 4 Port
measurement ... but I got all Parameters (s11, s21, s12, ..) as 16
separate files and distributed inside an excel sheet.
I did the re-combination of the data with ADS. I have "extended" some
Connectors in the past in the same way .. I just have not thought about
using this method also to combine different files. Thanks for the hint
there!
Regards
Hermann
