S-Parameter Conversion
S-parameter conversion function allows for conversion of measurement results (Sab) to the following parameters:
| Parameter | Equation |
|---|---|
| Impedance in reflection measurement (Zr) | |
| Admittance in reflection measurement (Yr) | |
| Impedance in transmission measurement (Zt) | |
| Admittance in transmission measurement (Yt) | |
| Inverse S-parameter | |
| Equivalent admittance in transmission shunt measurements (Ytsh) | |
| Equivalent impedance in transmission shunt measurements (Ztsh) | |
| S-parameter complex conjugate | |
| Z0a – characteristic impedance of Port a, |
| Note | Equations for Zr, Zt, Yr, Yt are approximate. The general method of converting S - parameters to Z, Y, H, T, ABCD - parameters is presented in the next section. The reason for using the approximate method is the measurement speed, as only one S – parameter is used in the calculations, whereas the general method requires measurement of the full matrix of S-parameters. | |

The S-parameter conversion function can be applied to an individual trace of a channel. Before enabling the function, first activate the trace.
