About Segment Sweep

GetXAxisValues2 Method

Description

Returns the channel's X-axis values into a dimensioned Typed array. GetXAxisValues2 is a convenient method for determining the frequency of each point when the points are not linearly spaced - as in segment sweep.

Note: This method will fail if called using a scripting client such as VBScript or Keysight Vee, (see remarks)

Note: In Segment Sweep, chan.NumberofPoints will return the total number of data points for the combined segments.

 VB Syntax

chan.GetXAxisValues2 numPts,data

Variable

(Type) - Description

chan

(object) - A Channel object

numPts

(long integer) - Number of data points in the channel

data

(double) Single dimensioned array of data matching the number of points in the channel.

Return Type

double

Default

Not applicable

Examples

Dim App As Application
Set App = New Application
Dim numPoints As Long
Dim values() As Double
numPoints = App.ActiveChannel.NumberOfPoints
ReDim values(numPoints)
App.ActiveChannel.GetXAxisValues2 numPoints, values(0)
Print values(0), values(1)

C++ Syntax

HRESULT GetXAxisValues2(long* pNumValues, double* stimulus)

Interface

IChannel

 

Remarks:

This method will fail if called using a scripting client such as VBScript or Keysight Vee. Use the GetXAxisValues method as a replacement for these COM environments.

This method also cannot be called using late-bound typing in Visual Basic. For instance, if, in the example above, the first line were replaced with "Dim App as Object", then this method would fail.
