Hi Andy,
I don’t understand this sentence:
>But when connecting the S1P block to standard 50 Ohm (real-impedance only) simulation port, with the “Ref” pin to GND, >or the return bus for the floating receiver circuit.
I expected a structure like “But when …, then…”.
Also, what do you mean with “floating receiver circuit”?
Maybe you want to correct your forum post?
Mind, that you acquired a s1p file, but are using a 2-port-symbol. It would not surprise me, that this gives random results. You can edit the number of ports in that block’s properties.
Best
Carsten
