Overview: User Defined Measurement and Reference Filters
The Modulation Parameters control tab for GP Digital Modulation displays enables you to load custom
measurement and reference filters. If the existing filters do not meet your requirements, you can create
your own filters for use in the measurement and reference settings. This section describes the structure of
user filters and provides two examples of customized filters. See
Loading a User Measurement Filter
To load a your own measurement filter:
1. From the Modulation Params control tab (Settings > Modulation Params), click on the drop-down
list for Measurement Filter.
2. Select one of the filter names that starts with User. This displays the Manage user filters window.
3. Enter a name for the filter in one of the Name (editable) boxes. This name will appear in the
drop-down list on the Modulation Params tab, prefaced with User. The maximum number of
characters for the filter name is 20.
