AnalogMultiEdgeStartTrigger.Hystereses Property
Specifies an array of hysteresis levels in the units of the measurement or generation. If the corresponding element of Start.AnlgMultiEdge.Slopes is Rising, the trigger does not deassert until the source signal passes below the corresponding element of Start.AnlgMultiEdge.Lvls minus the hysteresis. If Start.AnlgEdge.Slope is Falling, the trigger does not deassert until the source signal passes above Start.AnlgEdge.Lvl plus the hysteresis. Hysteresis is always enabled. Set this property to a non-zero value to use hysteresis. Each element of the array corresponds to a source in Start.AnlgMultiEdge.Srcs and an element in each of the other Analog Multi Edge property arrays, if they are not empty.

Property Value

Type: Double
Specifies an array of hysteresis levels in the units of the measurement or generation. If the corresponding element of Start.AnlgMultiEdge.Slopes is Rising, the trigger does not deassert until the source signal passes below the corresponding element of Start.AnlgMultiEdge.Lvls minus the hysteresis. If Start.AnlgEdge.Slope is Falling, the trigger does not deassert until the source signal passes above Start.AnlgEdge.Lvl plus the hysteresis. Hysteresis is always enabled. Set this property to a non-zero value to use hysteresis. Each element of the array corresponds to a source in Start.AnlgMultiEdge.Srcs and an element in each of the other Analog Multi Edge property arrays, if they are not empty.

Exceptions

ExceptionCondition
DaqExceptionThe NI-DAQmx driver returned an error.

Remarks

This property returns a copy of the actual array. Avoid calling this property within a for loop because it creates a copy for each iteration of the loop. Avoid using an indexer to set a member of the array because the indexer returns a copy of the object and has no effect on the actual object.
