This is a common parameter in pipeline commands, allowing the user to specify which type of signal should be evaluated as input. Signal type is the top level of the data tree hierarchy.

The parameter will appear in commands as /Signal_Types or /SIGNAL_TYPES.

For example:

• EVENT_LABEL
• ANALOG
• TARGET
• PARAMETERS
• FORCE
• COFP
• FREEMOMENT
• METRIC
• KINETIC_KINEMATIC
• LINK_MODEL_BASED
• DERIVED
• P2D

The Signal_Type parameter is often accompanied by two other parameters:

• Signal_Folder
• Signal_Names

Together these three parameters represent the application-wide data tree syntax.
