Triggers

The definition of a trigger depends on the device object. For analog input objects, a trigger is defined as an event with the action of initiating data logging to memory and/or a disk file. For an analog output object, a trigger is defined as an event with the action of sending queued data to the D/A converter. This is illustrated in the figure below.


An important concept in the Data Acquisition Toolbox for analog input objects is the number of samples to acquire for each channel group member per trigger. This number is used to specify how much data you want to store in the engine and is described in detail in "Configuring Triggers" in Chapter 4.
