network analyzer port software?

[biff44]

if I had a two port network analyzer, like an 8720 or 8722, but needed to measure a 3 port circulator...is there any software available to compute the 3 port S parameters from multiple 2 port measurements? I am particularly interested in if a full 3 port TRL cal can be "simulated" with the software.

Thanks

If you can get the data points into Excel, you could just calculate them.

There are quite a few papers about doing all of that:
