Setting a Range Function (2D and Circuit)
To apply a range function to the Y, Z, or Mag component of a trace:
- Click Range Function in the Reports window.
This opens the Set Range Function window. The functions available are the same as described in Selecting a Function.
- Click the Specified radio button on the Range function line.
This enables the Range Function fields.
- Select the Category, then an
associated Function to apply. The available categories depend on the
plot, and Category enables the display of associated functions.

Given a selected Function, and Category, the Set Range Function window displays a 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.
The Eye Measurement functions have five editable parameters.
- Click the Over Sweep drop-down menu to select from available sweeps.
- To select from available Sweeps, or to edit them, click [...] and uncheck Use All Sweeps.
This enables a list of the sweeps. The sweep(s) you select is displayed on the Over Sweep line. You can use the buttons to Clear All Selections or Select All sweeps.
- Select the Sweeps Default or Edited buttons to specify whether to accept the default or edited sweeps.
- To edit the sweeps further, select [...] to open the Edit Sweep window.
For frequency variables, this lets you specify a single value, linear step, linear count, decade count, or octave count. You can Add legal values to the list of sweep values, Update the list for changes, or Delete selected entries.
- Click OK to apply the range function.
