Z/REF - REF/Z


                 Z/Ref - Ref/Z

                 Convert between impedance and reflection coefficient.

                 1. Z to Ref. Coeff.
                 2. Ref. Coeff. to Z

                 Choose (1-2) [<Enter>=Quit] ? _


Let's try the Z to Ref. Coeff. conversion. Choose "1" from the list above and press <Enter>. Input "100,20,50" to specify an impedance of 100+j20 ohms in a 50 ohm system, and press <Enter> once again.

Here is the output calculation:

                Ref. Coeff. = 0.356 at 14.207 deg.

Try it back the other way using different data. Choose "2" and press <Enter>. Input "2.149,148.3,50" to specify the input reflection of a negative resistance oscillator as 2.149 at an angle of 148.3 degrees, in a 50 ohm system, and press <Enter> once again.

Here is the output calculation:

                Z = -18.505 +j 12.175 ohms
