Setting the Solution Quantity's Calculation Range

The calculation range of a solution quantity determines the intrinsic variable value at which the solution quantity is extracted. For a statistical setup, the calculation range must be a single value.For a Driven Modal or Driven Terminal design, if you specified that the solution be extracted from the last adaptive solution, Optimetrics uses the adaptive frequency defined in the solution setup. If you specified that the solution quantity be extracted from a frequency sweep solution, Optimetrics will use the starting frequency in the sweep by default.The calculation range should be set during the setup of the solution quantity for statistical evaluation. In order to modify the calculation range, do the following:

  1. Under the Calculations tab of the Setup Statistical Analysis dialog box, click in the Calculation Range column of the table for the calculation to be modified.

    The Edit Calculation Range dialog box appears.

  2. In the table, click Edit in the row to be modified.

    If you choose to solve a parametric setup during the statistical analysis, the variables swept in that parametric setup are available in the pop-up list dialog box. If you sweep a variable in the parametric setup that is also a statistics variable, that variable is excluded from the statistics analysis.

    Other examples of available variables include frequency, if you selected an S-parameter solution quantity; and phi or theta, if the solution quantity is a radiated field quantity.

  3. Click on the value for the calculation range in the list and dismiss the pop-up dialog box.
  4. Click OK in the Edit Calculation Range dialog box to accept the new value for the intrinsic variable and return to the Setup Statistical Analysis dialog box.
