HorOffset Double
From -0.0005 to 2.5e-007 step 1e-009 Range
Sets/Queries the horizontal position of the trigger time, relative to the origin set by HorOffsetOrigin, in
seconds. Positive to the right, negative to the left. The setting resolution is about 1% to 2&.
Description
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set the horizontal trigger offset to 200 ns.
app.Acquisition.Horizontal.HorOffset = 2.0e-7

HorOffsetOrigin Double
From 0 to 10 step 1 Range
Sets/Queries the origin, in graticule divisions, of the time scale in which HorOffset is measured.
The value 0 corresponds to the left edge of the graticule. The value 10 corresponds to the right edge
of the graticule. Requesting a value outside the range will select the nearest allowed value.
Description
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set the origin of the horizontal trigger offset to 4.0 divisions.
app.Acquisition.Horizontal.HorOffsetOrigin = 4.0
