In this dialog box, you may define which of the previously defined 1DC template-based postprocessing results is evaluated while the optimizer is running. In addition, you may define how the data will be evaluated.

Template Based Postprocessing frame

Result Name: You can select one 1DC template based post-processing result by its name out of a list of all previously defined 1DC template based postprocessing results using the respective drop-down list. This template-based post-processing result is evaluated while the optimizer is running.

Type

Specify the complex type of the 1DC result. You may select between Mag. (linear), Mag. (dB), Phase, Real Part or Imaginary Part.

Conditions frame

Operator: You may select an operator from this drop list. The operator affects the way the data is being evaluated during an optimization run. Currently, five different operators are available for general 1D template based post-processing result goals. Two addition operators are available if the goal corresponds with the amplitude of an S-Parameter template.

<: The optimizer tries to find a parameter setting where the value of the evaluated result template is lower than the given target.

>: The optimizer tries to find a parameter setting where the value of the evaluated result template is greater than the given target.

=: The optimizer tries to find a parameter setting where the value of the evaluated result template equals the given target.

min: This operator is only available for 1D and 1DC results based on the amplitude or dB entity of an S-Parameter template. Then the optimizer tries to minimize the S-Parameter data. Minimizing the S-Parameter data means that the optimizer tries to find a parameter setting where the maximum of the S-Parameters over the given frequency range is as low as possible.

max: This operator is only available for 1D and 1DC results based on the amplitude or dB entity of an S-Parameter template. Then the optimizer tries to maximize the S-Parameter data. Maximizing the S-Parameter data means that the optimizer tries to find a parameter setting where the minimum of the S-Parameters over the given frequency range is as high as possible.

move min: This operator is only available for 1D and 1DC results. Use this operator if you want to minimize the abscissa distance of the minimum of the 1DC result to the selected target. Keep in mind that sensitivities can't be exploited if this goal is used because the min operator is not differentiable. In contrast to the other goal operators (except of move max) the Target of move min corresponds with an abscissa value of the result instead of an ordinate value.

move max: This operator is only available for 1D and 1DC results. Use this operator if you want to minimize the distance of the maximum of the 1DC result to the selected target. Keep in mind that sensitivities can't be exploited if this goal is used because the max operator is not differentiable. In contrast to the other goal operators (except of move min) the Target of move max corresponds with an abscissa value of the result instead of an ordinate value.

Target: Enter a target value for the chosen operator here if the corresponding result entity should be "less", "greater" or "equal" than that certain target in the chosen range. For the "move min" or "move max" operator the optimizer will try to move the minimum or the maximum of the template's result to the chosen target value.

Weight: Enter the weight of this goal here.

Range frame

Specify a range or a single abscissa value for which the goal is evaluated. The range is limited by the lowest abscissa value and the highest abscissa value of the specified data.

The value of the optimizer goal will be the maximal error of the result in the given range with respect to the defined goal operator.

Total: Set the range to the maximum range of the corresponding result.

Single: Set the single range value. The optimizer will extract only one point from the 1DC template based post-processing result data.  Please note the limits.

Range: Set the range in which the goal should be defined.

OK

Stores the current settings and returns to the Optimizer - Goals property page. The newly defined goal is added to the list of defined goals in the Optimizer - Goals property page.

Closes this dialog box without performing any further action.
