Hi Marco Wyss,
As per my understanding to your question, you have the complex s-parmeters data and you are looking to generate the sparameter object for the same. yes it is possible.
You can use sparameters() by passing sparams values as the first input argument and frequency as a second positional input argument, they are the required inputs to sparameter function. Please look at the example code below for more understanding.
length = 1e-3;
freq = 1e9;
z0 = 50;
R = 50;
L = 1e-9;
G = .01;
C = 1e-12;
s_params = rlgc2s(R,L,G,C,length,freq,z0);
% Get the sparams object
sobj = sparameters(s_params,freq)
sobj = sparameters(s_params,freq,z0)
You can refer to the following documentation to know more about sparameters().
Thanks,
