How to add S parameters in two port sweep?

When I execute the S-parameter port sweep in a two port device the solutions for S11 and S12 are in different parameter sweep groups. Therefor, I cannot plot 20*log10(abs(emw.S11+emw.S12)) because both have to be in the same solution group and S11 and S12 are in different groups. How can I do this operation? Is there a function to select from a parametric sweep?

Thanks in advance!

Robert,

check the with() and withsol() operators. They allow to reference specific parametric solutions.

Cheers Edgar

Thanks Edgar, I tried this but when I select for a specific parameter it will only take the last of the frequency sweep instead of each corresponding one. Any workaround?

you must include the frequency in the withsol() call, so one of the expressions in the call has to be 'setval(freq, freq)', exactly like this.
