Handshake Trigger
A Handshake Trigger is a control signal from a peripheral device. The peripheral device asserts the Handshake Trigger to signal to the DAQ device that it has acquired a sample (for output tasks) or generated a sample (for input tasks). For input tasks, the DAQ device latches data, by default, at the trigger position specified by the sample when attribute/property when the peripheral device deasserts the Handshake Trigger.
