Configuring Analog Output Triggers

An analog output trigger is defined as an event that initiates the output of data. As shown in the figure below, when a trigger occurs, the Sending property is automatically set to On and queued data is output from the engine to the hardware subsystem.

Properties associated with analog output triggers are given below.

InitialTriggerTime
Indicate the absolute time of the first trigger.

TriggerFcn
Specify the M-file callback function to execute when a trigger occurs.

TriggersExecuted
Indicate the number of triggers that execute.

TriggerType
Specify the type of trigger to execute.

**Table 6-7: Analog Output Trigger Properties**
Property Name	Description
