Hi, experts, I get two identical fixtures on both sides of my DUT. And I got the s4p data of the fixture itself and s4p data of the DUT cascading with the two fixtures. Could you please kindly let me know how I can de-embed the fixture and get the s4p data for the DUT? I know the math behind it but the data itself is too big to calculate. Thanks in advance.
