on Jan 9, 2013I am trying to setup a schematic that concatenates 2 S-Parameter blocks and I want to also deembed a 2-port s-parameter component from port 1 of this schematic. the difficulty (or challenge) is that the S-Matrix data for the deembeding is the result of a calculation and not a pre-existing S2P file or dataset. here is what I have attempted to do:

The equation that I want is in the var "PathDiff", but I can't figure out how to make the S2P De-Embedding component use the data from that var. I know that this might be easier to do in a display view, but I have to repeat this process multiple times and I need to experiment with changing the underlying S-Parameter values that are in DAC1 and DAC2, so figuring out a way to do it in the schematic view will be much more convenient for what I am doing. I should also note that I am not insistent in using DAC to access the individual s-parameter blocks. I also have separate schematics that represent each individual S2P file that I have. So, if there is a better way to do this without the DAC component, then I am open to any suggestions.
Thanks.
