You can specify SequenceStepDeltaTime as one of the properties when calling the CreateAdvancedSequence method. In this case, this property specifies the amount of time between the start of the active step and the start of the next step.

This property is applicable only if the SequenceStepDeltaTimeEnabled property is set to true. Refer to the SequenceStepDeltaTimeEnabled property for more information about the settings with which this property is compatible. This property does not apply to the last step of the last iteration of a sequence.

You can set values for the SourceDelay and Measurement properties in conjunction with this property. Values for SourceDelay may conflict with the value of this property; Measurement properties may conflict with the value of this property only if the MeasureWhen property is set to AutomaticallyAfterSourceComplete.

Note

This property is not supported by all instruments. Refer to the Supported Properties by Device topic in the NI DC Power Supplies and SMUs Help for information about supported instruments.

Note

Refer to the Sequence Step Delta Time topic in the NI DC Power Supplies and SMUs Help for more information.
