Selecting Solution Quantities to Plot (2D and Circuit)

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 Electronics Desktop 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 window, 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 on the original field solution.
   S-parameter	S-parameters on 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 on the S-parameters and port impedances.
   Z-parameter	Impedance matrix parameters computed on 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 on the equation .

   
   
2. Select a quantity to plot on the Quantity group box. The available quantities depends upon the selected category and the setup of the design.
