Then you can calculate \$S_{11} = \frac{Z_{in}-Z_0}{Z_{in}+Z_0}\$. You're trying to measure the properties of your 2-port, not trying to optimize the system to work with your 2-port. | |
| Oct 21, 2020 at 19:31 | comment | added | brian736 | I see thank you for pointing out what I did wrong clearly, so say I wanted to calculate S11, now that Z_0 is assumed to be 50 ohms the goal is to terminate Port 2 with a resistor that creates an input impedance of 50ohms as well correct? Such that the reflection coefficient = 0? Or is port 2 also terminated with 50 ohms? | |
