Chapter Three Control Reference
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.
PersistenceSaturation
From 0 to 100 step 1
Integer
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set the persistence saturation level for trace F1.
app.Math.F1.PersistenceSaturation = 40
Range
Example
Description
Sets/Queries the state of the Show Last Trace control. If True then when this trace is displayed in
persistence mode the last acquired waveform will be superimposed on the accumulating persistence
map. See the general description above for a discussion of the locked and unlocked persistence
modes.
ShowLastTrace Bool
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Do not show the last trace for the persistence trace of trace F1.
app.Math.F1.ShowLastTrace = False
Example
Description
Sets/Queries the state of the Persistence Time control. Controls the persistence decay time for this
trace. See the general description above for a discussion of the locked and unlocked persistence
modes.
PersistenceTime Enum
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set the persistence time for the trace F1 to 10 seconds.
app.Math.F1.PersistenceTime = "10s"
