Data Type: float64
Description: Specifies the actual amount of excitation supplied by an internal excitation source. If you read an internal excitation source more precisely with an external device, set this property to the value you read. NI-DAQmx ignores this value for external excitation. When performing shunt calibration, some devices set this property automatically.


You can get/set/reset this property using:

  DAQmxGetAIExcitActualVal

  DAQmxSetAIExcitActualVal

  DAQmxResetAIExcitActualVal
