Turns on/off TDR Normalized trace variable vertical zoom
VariableVerZoom Bool
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Turn off TDR normalized trace variable vertical zoom scale
app.TDR.TDRN.Zoom.VariableVerrZoom = "Off"
Example
Description
Turns on/off TDR Normalized trace variable horizontal zoom
VariableHorZoom Bool
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Turn on TDR normalized trace variable horizontal zoom scale
app.TDR.TDRN.Zoom.VariableHorZoom = "On"
Example
Description
TDR Normalized trace vertical zoom
VerZoom
From 0.1 to 100 step (8 digits)
Double
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Assuming the normalized trace shows impedance parameter
' Change TDR normalized trace vertical scale per division to 10 ohms
app.TDR.TDRN.Zoom.VerZoom = 10
Range
Example
Description
TDR Normalized trace vertical position
VerPos
From -1.5 to 1.5 step (8 digits)
Double
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Assuming the normalized trace shows S parameters
' Change TDR normalized trace center vertical position to start at -10dB
app.TDR.TDRN.Zoom.VerrPos = -10
