When you set the NIRFSA_ATTR_REF_TRIGGER_TYPE attribute to NIRFSA_VAL_IQ_ANALOG_EDGE, the device asserts the trigger when the signal level exceeds the specified level with the slope you specify. This attribute affects the device operation only when the NIRFSA_ATTR_REF_TRIGGER_TYPE attribute is set to NIRFSA_VAL_IQ_ANALOG_EDGE.
