NI-DAQmx C Properties

Start >> Analog Edge >> Hysteresis

Data Type: float64
Description: Specifies a hysteresis level in the units of the measurement or generation. 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.
