Does anyone know if there is an available conversion routine (e.g. Excel, Mathad, web-based.....), that would help me convert multiple 2-port VNA S-parameters obtained on a 4-port DUT (measure all combinations of two-ports while the other ports are terminated) and convert them into 4-port mixed-mode S-parameters? I am especially interested in SCC21 and SDC21 (CM-CM transfer and CM- DM conversion). I cannot use TDR/TDT because I need at least -60 dB sensitivity.
