PropertyDescription
Start:Trigger Type Specifies the type of trigger to use to start a task. Details
Start:Terminal Indicates the name of the internal Start Trigger terminal for the task. This property does not return the name of the trigger source terminal. Details
Start:Digital Edge:Source Specifies the name of a terminal where there is a digital signal to use as the source of the Start Trigger. Details
Start:Digital Edge:Edge Specifies on which edge of a digital pulse to start acquiring or generating samples. Details

Start:Digital Edge:Digital Synchronization:Enable Specifies whether to synchronize recognition of transitions in the signal to the internal timebase of the device. If you set this property to TRUE, the device does not recognize and act upon the trigger until the next pulse of the internal timebase. Details

Start:More:Trigger Window Specifies the period of time in seconds after the task starts during which the device may trigger. Once the window has expired, the device stops detecting triggers, and the task will finish after the device finishes acquiring post-trigger samples for any triggers detected.

Ensure the period of time specified covers the entire time span desired for trigger detection to avoid missed triggers. Specifying a Trigger Window of -1 causes the window to be infinite. Details
Start:More:Retrigger Window Specifies the period of time in seconds after each trigger during which the device may trigger. Once the window has expired, the device stops detecting triggers, and the task will finish after the device finishes acquiring post-trigger samples that it already started.

Start:More:Maximum Number of Triggers to Detect Specifies the maximum number of times the task will detect a start trigger during the task. The number of times a trigger is detected and acted upon by the module may be less than the specified amount if the task stops early because of trigger/retrigger window expiration. Specifying the Maximum Number of Triggers to Detect to be 0 causes the driver to automatically set this value to the maximum possible number of triggers detectable by the device and configuration combination. Note: The number of detected triggers may be less than number of trigger events occurring, because the devices were unable to respond to the trigger. Details
