ShowLastTrace Bool
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.
Description
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Makes the last acquired trace invisible for the
' persistence trace of channel C1.
app.Acquisition.C1.ShowLastTrace = False
Example
UseGrid String
Any number of characters Range
Sets/Queries the graticule on which the trace is displayed. Typical values include:
YT1..YT8: one of the YT graticules used in Single, Dual, Quad, and Octal display modes.
NotOnGrid: not displayed on any graticule.
Description
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Switch to dual grid mode, place C1 on the lower graticule
' and C2 on the upper graticule.
app.Display.GridMode = "Dual"
app.Acquisition.C1.UseGrid = "YT2"
app.Acquisition.C2.UseGrid = "YT1"
Example
VerOffset Double
From -1 to 1 step 0.0005 Range
Sets/Queries the vertical offset of input channel Cx. The setting resolution in volts lies in the range
0.25% to 0.5%, depending on the numerical value.
Note that the available offset range is dependent upon the current V/Div setting, and also the
instrument model.
Description
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set the vertical offset for C1 to 10 mV.
app.Acquisition.C1.VerOffset = 0.01
