Hi,
if I run a psp-Analyses and plot "spm('psp 1 1)", this is plotted in a smith-chart. But if I plot "spm('psp 1 1)-spm('psp 2 1)-spm('psp 1 2)+spm('psp 2 2)" which is the differential-differential-S-parameter (Sdd), this is plotted in a rectangular chart. How can I plot such a sum/difference into a smith-chart? I want to add this expression into ADE GXL. IC 6.1.6.
Thank you and happy new year!
