Setting a Range Function

To apply a range function to the Y, Z, or Mag component of a trace:

Note: All range functions are available in the list regardless of solution context. You must select a function that is appropriate for the solution context and data type you are working with.
  1. Click the Range Function button in the Reports dialog box.

    2. This opens the Set Range Function dialog. The functions available are the same as described in the Selecting a Function section, with the exception of those for the Eye Measurements category.

  2. Click the Specified radio button on the Range function line.

    3. This enables the Range Function fields.

  3. Select the Category, and then an associated Function to apply. The available categories depend on the plot, and Category enables the display of associated functions.

    4. Given a selected Function, and Category, the Set Range Function dialog displays a text field that explains the Purpose of the function. For a full list of functions and their definitions, see Selecting a Function.

    Selecting a function causes the display of a description in the Purpose field. If the function requires a value (such as the XatYVal Math function or the pw_minus_max Pulse Width function), the following table the function field displays the name, editable value field, unit, and description.

  4. Use the Over Sweep drop down menu to select from available sweeps.
  5. To select from available Sweeps, or to edit them, click the ellipsis [...] button to display a dialog box that lets you select particular sweep values, specify a range of sweep values (for Time sweeps). By default, Use all values is selected.
    • For sweeps other than Time, unchecking Use all values enables a list of available sweep values. You can use the buttons to Clear All or Select All sweep values.
      1. Select the Sweeps Default or Edited radio buttons to specify whether to accept the default or edited sweeps.
      2. To edit the sweeps further, select the ellipsis [...] button to display an Edit Sweep dialog box. For frequency variables, this lets you specify a single value, linear step, linear count, decade count, octave count, or exponential count. You can Add legal values to the list of sweep values, Update the list for changes, or Delete selected entries.
      3. When finished selecting/editing sweep values, close the dialog box. The sweep values you select are displayed on the Over Sweep line.
    • For Time sweeps:
      1. Select the Specify range radio button to enable the Min and Max value fields.
      2. Enter the desired Min and Max values, and choose the associated units of measure from the drop down lists.
      3. When finished, close the dialog box. The sweep values you select are displayed on the Over Sweep line.
  6. Click OK to apply the range function.
