Persist3DQuality Enum
Sets/Queries the state of the 3D Persistence quality control. Control the way that the persistence trace
is rendered. 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 persistence 3-D to shaded for trace F1
app.Math.F1.Persist3DQuality = "Shaded"
Example
Values
Shaded
Solid

PersistDotJoined Bool
If this control is false (the default state), then samples are put into the persistence map as dots. The
advantage of that is that any lit pixel in the pmap actually corresponds to a sample of the data taken at
that time. The disadvantage of dots is that there is no way to associate a dot with any other dot; there
is no history of which dots were part of the same acquisition. If this control is set to true, then each
acquisition draws lines into the persistence map that connect the dots at the sample positions. Clearly
the advantage of that is that it is now possible to see if some outlier samples were all part of the same
acquisition, or not. The disadvantage is that lit points in the persistence map no longer correspond to
actual samples, the lines between the samples are also lit. If the persistence map is going to be
analyzed it is probably preferable to leave Dot Joined off so that only actual samples are considered in
the analysis.
If there are very few points in a persistence map, there may columns with no points, that is, there are
gaps horizontally between points. Dot Joined will connect them starting with the last trace, and for all
subsequence traces accumulated. The action of turning on or off Dot Joined clears the accumulated
persistence map.
Description
Persisted Bool
Sets/Queries the persisted state of the function 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 F3.
app.Math.F3.Persisted = True
