Chapter Three Control Reference
Queries the number of samples in the current setting of the acquisition memory. For sequence mode,
this refers to the number if samples per segment, not to the number in the complete set.
Use MaxSamples to limit the number of samples acquired.
NumPoints
From 2 to 512000000 step 1
Integer
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Obtain the number of points being used in the acquisition memory.
NumberOfPoints = app.Acquisition.Horizontal.NumPoints
MsgBox NumberOfPoints
Range
Example
Description
Queries the time interval between successive samples in the acquisition.
TimePerPoint
From 5e-015 to 1e+012 step 1e-013
Double
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Obtain the time per point of the acquisition.
timePerPt = app.Acquisition.Horizontal.TimePerPoint
MsgBox timePerPt
Range
Example
Description
Sets/Queries the mode of acquisition as real-time or sequence or random interleaved sampling. Note
that RIS mode and sequence mode are not available over the entire range of time-bases, and are not
available simultaneously.
WaveExpert differences: CIS and SEQ are the only timebase modes.
SampleMode Enum
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set the mode of acquisition to random interleaved sampling.
app.Acquisition.Horizontal.SampleMode = "RIS"
' WaveExpert example
app.Acquisition.Horizontal.SampleMode = "CIS"
