Data Acquisition Toolbox

Executing the Trigger

For an analog input trigger to occur, you must follow these steps:

1. Configure the appropriate trigger properties.
2. Issue the start function.
3. Issue the trigger function if TriggerType value is Manual.

Once the trigger occurs, data logging is initiated. The device object and hardware device stop executing when the requested samples are acquired, a run-time error occurs, or you issue the stop function.

Note    After a trigger occurs, the number of samples specified by SamplesPerTrigger is acquired for each channel group member before the next trigger can occur.
