NIFGEN_ATTR_TRIGGER_SOURCE
IviFgenTrigger Attribute
| Data Type | Access | Applies to | Coercion | High-Level Functions |
|---|---|---|---|---|
| ViInt32 | R/W | Channel | None | niFgen_ConfigureTriggerSource |
Description
Controls which trigger source the signal generator uses.
After you call the niFgen_InitiateGeneration function, the signal generator waits for the trigger that you specify in the triggerSource parameter in the niFgen_ConfigureTriggerSource function. After the signal generator receives a trigger, it produces the number of cycles that you specify in the NIFGEN_ATTR_CYCLE_COUNT function.
This attribute is also the source for the trigger in the other trigger modes as specified by the NIFGEN_ATTR_TRIGGER_MODE attribute.
