Data Access Map

Description

Retrieves pairs of data 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.getPairedData location, format, numPts, d1, d2

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.

See Data Access Map

format

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

0 -naLogMagPhase - Log magnitude and phase

1 -naLinMagPhase - Linear magnitude and phase

2 -naRealImaginary - Real and Imaginary

Note: Selecting naRealImaginary format is the same as using the getComplex method

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 dPaired array

d1

(single) - Array to store the magnitude / real values

d2

(single) - Array to store the phase / imaginary values

Return Type

Two Single arrays

Default

Not Applicable

Examples

Dim logm() As Single
Dim phase() As Single
Public measData As IArrayTransfer
Set measData = app.ActiveMeasurement
Dim numpts As Long
numPoints = app.ActiveChannel.NumberOfPoints
ReDim logm(numPoints)
ReDim phase(numPoints)

measData.getPairedData naCorrectedData, naLogMagPhase, numPoints, logm(0), phase(0)

Print values(0), values(1)

C++ Syntax

HRESULT getPairedData(tagNADataStore DataStore, tagNAPairedDataFormat PairFormat, long* pNumValues, float* pReal, float* pImag)
