I have a three port S-parameter file with port 1 as a single ended input and ports two and three froming a differential pair as the output. I want to meaure the transfer function between ports 1 and the output differential pair and I'm not sure how to set it up. I would think the transsfer voltage function from one with a sense across 2 and three. Not sure how to do that with the input and output ports available.
