hi all,

as there is one button features measurement for K factor for PNA, i find out we did not have any commands available in the help file, if let say we want to incorporate this K factor measurement into VEE program, i wonder anyone here has the readily own written VEE program for the K factor?

or any source code is available? thanks for your help.

But anyway, there is a K-Factor function in the equation editor. Go to Analysis, Equation editor, scroll down to the K's and you will see it, along with Mu1 and Mu2. It is setup for ports 1 and 2 already. Just click on the function, and you will have what you need!

From the PNA help page:

kfac(complex a, complex b, complex c, complex d )

when entered in EE:

kfac(S11,S21,S12,S22)

k-factor:

k = (1 - |a|^2 - |d|^2 + |a*d-b*c|^2 ) / (2 * |b*c|)

returns a scalar result - the imaginary part of the complex result is always 0
