In the display window of s parameter simulation,there are several different noise parameters, such as nf(1),nf(2),ans nfmin, what are the defference and the relation between these parameters?

Thanks!
 

nf(1) is the noise figure when port 1 is treated as output;
nf(2) is the noise figure when port 2 is treated as output;
nfmin is the minimum noise figure of the two-port, and together with the other three parameters(the complex optimum impedance and the real coefficient Rn), the noise property of the two-port can be completely decided.
