ScopeChannelMeasurement.FetchArrayMeasurement Method (PrecisionTimeSpan, ScopeArrayMeasurementType, AnalogWaveformCollection(Double))

public AnalogWaveformCollection<double> FetchArrayMeasurement(
	PrecisionTimeSpan timeout,
	ScopeArrayMeasurementType arrayMeasurementType,
	AnalogWaveformCollection<double> measurementWaveforms
)

Public Function FetchArrayMeasurement ( 
	timeout As PrecisionTimeSpan,
	arrayMeasurementType As ScopeArrayMeasurementType,
	measurementWaveforms As AnalogWaveformCollection(Of Double)
) As AnalogWaveformCollection(Of Double)

Parameters

timeout

Type: NationalInstrumentsPrecisionTimeSpan
The time to wait for data to be acquired. Using 0 for this parameter tells NI-SCOPE to fetch whatever is currently available. Using -1 for this parameter implies infinite timeout.

arrayMeasurementType

Type: NationalInstruments.ModularInstruments.NIScopeScopeArrayMeasurementType
The type of the array measurement to perform.

measurementWaveforms

Type: NationalInstrumentsAnalogWaveformCollectionDouble
The waveform object whose memory can be reused while creating the output waveform. To allocate memory during the call to this method, set measurementWaveforms to . The method will also allocate memory during the call if measurementWaveforms is set to a waveform object with zero-sized data or measurementWaveforms is set to a waveform object with a different size than that required for the output waveform. For example, if measurementWaveforms is set to a waveform object with the same size as that required for this method call, then no new memory is allocated for the output waveform, and instead the memory of the waveform object from measurementWaveforms will be reused for the output waveform.
