Selecting Solution Quantities to Plot

When you create a report of Modal or Terminal solution data, each trace in the report includes a quantity that is plotted along an axis. The quantity being plotted can be a value that was calculated by Designer such as S₁₁, a value from a calculated expression, or an intrinsic (inherent) variable value such as frequency or theta. The valid categories available depend on the type of quantity (real or complex) that is being plotted, the setup, the solution type, and the plot domain.

To select an S-parameter quantity to plot:

1. In the Report dialog box, Trace tab, select one of the following categories:

Variables

Intrinsic variables, such as frequency or theta, or user-defined project variables, such as the length of a quarter-wave transformer.

Output Variables

User defined expressions applied to derive quantities from the original field solution.

S-parameter

S-parameters from the S-matrix. For designs which include a Frequency Selective Surface (FSS)-referenced radiation boundary, S11 and S21 represent the extracted reflection and transmission coefficients, respectively.

Y-parameter

Admittance matrix parameters computed from the S-parameters and port impedances.

Z-parameter

Impedance matrix parameters computed from the S-parameters and port impedances.

Gamma

Propagation constants for the S-parameters.

Port Z_o

Characteristic port impedances.

VSWR

Voltage standing wave ratio, calculated from the equation .

2. Select a quantity to plot from the Quantity list. The available quantities will depend upon the selected category and the setup of the design.
