Hi,

"VNA Tools" is free, and very comprehensive, but using it is another matter. I think they expect people to pay for training (or you'll spend quite a while self-studying).

There is also SimNEC (also known as SimSmith, but that's the older version). That allows you to add any L and C and see the effect on the smith chart. Perhaps you can directly add R values I've no idea, there are user guides for it and an mailer group. In any case you can indirectly do it by adding a Q value. You can add attenuation too (by inserting transmission line; maybe there are other options too, you'd need to check the user guides).
