Automation Command and Query Reference Manual - Control Reference
LabelsPosition String
Any number of characters Range
Sets / Queries the horizontal position of the label attached to the acquisition trace Cx. The unit of
measurement is the unit of the horizontal scale. The measurement is made from the trigger point.
Note that this control is a string, not a numeric value. This allows multiple labels to be positioned, as
shown in the example below.
Description
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Add a couple of labels to trace C1, one at 0ns, and one at 55ns
app.SetToDefaultSetup
app.Acquisition.C1.ViewLabels = True
app.Acquisition.C1.LabelsPosition = "0.0,55e-9"
app.Acquisition.C1.LabelsText = "Hello,World"
Example
LabelsText String
Any number of characters Range
Persisted Bool
Sets/Queries the persisted state of the waveform. If the Display.LockPersistence control is set to
'AllLocked' then the persisted state of all displayed waveforms will be the same. If the
Display.LockPersistence control is set to 'PerTrace' then the persisted state of each waveform may be
independently controlled.
Description
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set persistence on for trace C1
app.Display.LockPersistence = "PerTrace"
app.Acquisition.C1.Persisted = True
Example
PersistenceSaturation Integer
From 0 to 100 step 1 Range
Sets/Queries the saturation threshold for persisted waveforms.
All information at this level or above will be recorded with the same color or intensity.
See the general description above for a discussion of the locked and unlocked persistence modes.
Description
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set the persistence saturation level for trace C1.
app.Acquisition.C1.PersistenceSaturation = 60
Example
1-16
