About ports

analogy

Lets say that you have a two port network.If the output port isn't matched to 50 Ohms, is it still safe to use output port resistance as 50 Ohms and get ZM2 ?


Secondly , if the output isn't matched, what should be the port resistance ?

Thanks.

  • Yes, you can still use a 50 ohm port impedance and the ZM2 output on the direct plot form should give you the circuit impedance looking in from the second port. Using a 50 port impedance should be OK for most s-parameter measurements (I guess it depends on what you're trying to do).
