Renormalize S-Parameter
Signal Post Processing  S-Parameter Calculations Renormalize S-Parameter...
S-Parameters are calculated for every port, or every input/output channel
of the project; these always have a reference impedance. This dialog box
offers recalculation with a new reference impedance; therefore, all of
the ports including the reference impedances are listed. For a full recalculation,
the complete set of s-parameters is necessary. Anyway, a recalculation
on a subset of S-Parameters can be done if all port modes that were not
excited are excluded.
(To calculate all S-Parameters, enter the Transient Solver dialog box and
select All
in the Port
entry field.)
To assign a new reference impedance to a port, select it in the List
of Ports, enter the new impedance value in the New Z Norm field, and finally
press RETURN to set the value.
List of ports
The List of Ports gives you an overview of all
the ports.
Several characteristics are listed here, such
as port number, mode, mode type and the related impedances.
Port
In this column, the port number identifying
the port is displayed.
Mode
The mode pattern for which S-Parameters and
reference impedance are calculated is listed here.
Type
The mode type which can be one of the following
: TE, TM, TEM, Quasi TEM and Unknown, is added here.
Z-Wave
The wave impedance (E/H) is listed here.
Z-Line
The line impedance for TEM and Quasi TEM modes
is listed here.
Z-Normalize
The currently used reference impedance is shown
here.
N Flag
The N–Flag shows you whether or the reference
impedance varies with frequency (VAR) or not (CONS).
Normalization Imp.
Enter a new reference impedance for a previously
selected port here. The new reference impedance is set as soon as the
RETURN key is pressed.
Unnormalize
Resets each reference impedance to its original
value.
OK
Accepts your settings and leaves the dialog
box.
Cancel
Closes this dialog box without performing any
further action.
