The following Chord operators are available for use with newer encoding formats.

User-Defined Waveform Operators

User-defined operators are custom operators that modify an input waveform. You create these operators using Python, MATLAB, or Compiled MATLAB. Like FlexDCA's standard operators, user operators filter an input waveform and display an output waveform. Two versions of the user operator are available: a single and a dual input waveform versions. To configure your operator, you first create a script and then a simple XML configuration file that points to your script. The XML file also creates different input fields on the User Operator Setup dialog.

To create a user-defined operator

1. Write a MATLAB or Python script that creates your operator.
2. Write an XML file that describes the operator and identifies the script.
3. Import the XML file into the User Operator Setup dialog.
4. Use the Waveform Signal Processing dialog box to select and assign a waveform to your operator.

User operators can do much more than simply run the your script. You can setup the operator to customize your script at runtime. For example, you can initialize variables within your script and create up to four user-defined controls on the dialog. Values that you enter or select in user-defined controls are passed to your script. The following types of user-defined controls can be created with the picture showing integer, double, string, and drop-down list controls.

Click the Display Setup tab to control the output waveform's display properties such as scaling, color, and custom waveform name.

Available controls: Integer value Double value Drop-down list of selections String File name
