Data Type: float64
Description: Specifies a hysteresis level in the units of the measurement. If Slope is DAQmx_Val_RisingSlope, the trigger does not deassert until the source signal passes below Level minus the hysteresis. If Slope is DAQmx_Val_FallingSlope, the trigger does not deassert until the source signal passes above Level plus the hysteresis. Hysteresis is always enabled. Set this property to a non-zero value to use hysteresis.


You can get/set/reset this property using:

  DAQmxGetAnlgEdgeRefTrigHyst

  DAQmxSetAnlgEdgeRefTrigHyst
