NI-DAQ™mx C Reference

More >> Pause >> Analog Level >> Hysteresis

Data Type: float64
Description: Specifies a hysteresis level in the units of the measurement or generation. If Pause When is DAQmx_Val_AboveLvl, the trigger does not deassert until the source signal passes below Level minus the hysteresis. If Pause When is DAQmx_Val_BelowLvl, 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:
  DAQmxGetAnlgLvlPauseTrigHyst
  DAQmxSetAnlgLvlPauseTrigHyst
  DAQmxResetAnlgLvlPauseTrigHyst
