Custom Chord Operators

The following Chord Signaling operators are available for use with newer encoding formats. An operator's output is automatically assigned to an output function. The function's waveform is not displayed unless you drag a function color icon onto the function's output. After placing chord operator, click on it to setup any available settings.

User-Defined Waveform Operators

User-defined operators are custom operators that are based on Python 2.7, Python 3, or MATLAB scripts. Like FlexDCA's standard operators, user operators that modify 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 create a user-defined operator

1. Write a Python, MATLAB, or Compiled MATLAB script that creates your operator.
2. Write an XML configuration file that:
• Describes the operator,
• Points to your script, and
• Creates different input variables to be displayed on the User Operator Setup dialog.
3. Import the XML file into the User Operator Setup dialog.
4. Use the Waveform Signal Processing dialog 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
