The S-parameter conversion function allows for the conversion of measurement results () to the following parameters:
Parameter |
Equation |
|---|---|
Impedance in reflection measurement () |
|
Admittance in reflection measurement () |
|
Impedance in transmission measurement () |
|
Admittance in transmission measurement () |
|
Inverse S-parameter |
|
Equivalent admittance in transmission shunt measurements () |
|
Equivalent impedance in transmission shunt measurements () |
|
S-parameter complex conjugate |
|
is characteristic impedance of Port a. is characteristic impedance of Port b. is measured S-parameter ( and are the port identifiers). , |
|
note |
Equations for , , , are approximate. The reason for using the approximate method is the measurement speed, as only one S-parameter is used in the calculations. |
The S-parameter conversion function can be applied to an individual trace of a channel. The trace to which the function is applied must be preselected as active (See Selection of Active Trace/Channel).

To enable/disable the conversion, use the following softkeys: Analysis > Conversion > Conversion |
|
To select the conversion type, use the following softkeys: Analysis > Conversion > Function Then select the required function: •Zr: Reflection •Zt: Transmission •Yr: Reflection •Yt: Transmission • 1/S: Inverse • Ztsh: Trans-Shunt •Ytsh: Trans-Shunt •Conjugation |
