GetScalar Method

Description

Retrieves scalar data (ONE number per data point) from the specified location.

Note: This method exists on a non-default interface. If you cannot access this method, use the Get Data Method on IMeasurement.

 VB Syntax

measData.getScalar location, format, numPts, data

Variable

(Type) - Description

measData

An IArrayTransfer interface which supports the Measurement object

location

(enum NADataStore) - Where the data you want is residing. Choose from:

0 - naRawData

1 - naCorrectedData

2 - naMeasResult

3 - naRawMemory

4 - naMemoryResult

5 - naDivisor - When reading data from, or writing data to, the normalization divisor, you must first create a divisor trace using DataToDivisor Method.

format

(enum NADataFormat) - Format in which you would like the data. Choose from:

0 - naDataFormat_LinMag

1 - naDataFormat_LogMag

2 - naDataFormat_Phase

3 - naDataFormat_Polar

4 - naDataFormat_Smith

5 - naDataFormat_Delay

6 - naDataFormat_Real

7 - naDataFormat_Imaginary

8 - naDataFormat_SWR

9 - naDataFormat_PhaseUnwrapped

10 - naDataFormat_InverseSmith

11 - naDataFormat_Kelvin

12 - naDataFormat_Fahrenheit

13 - naDataFormat_Centigrade

Note: Polar, Smith, and Inverse Smith are invalid formats for this command. See Get Complex Method.

Learn more about Data Format.

numPts

(long integer) - Number of data points requested
[out] - specifies number of data elements returned
[in] - specifies the data being requested or the capacity of the dScalar array

data

(single) - Array to store the scalar data.

Return Type

Single

Default

Not Applicable

Examples

Dim dScalar() As Single
Dim measData As IArrayTransfer
Set measData = app.ActiveMeasurement
Dim numpts as Long
numpts = app.ActiveChannel.NumberOfPoints
ReDim dScalar(numPoints)

measData.getScalar naCorrectedData, naDataFormat_LogMag, numpts, dScalar(0)
Print dScalar(0), dScalar(1)

C++ Syntax

HRESULT getScalar(tagNADataStore DataStore, tagNADataFormat DataFormat, long* pNumValues, float* pVals)

Interface

IArrayTransfer
