ENVELOPE
app.Math.Fx.OperatorYSetup (Operator = "Envelope")
Envelope of minimum and maximum values for an ensemble of sweeps, or 'Extrema'
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Configure F3 to be an envelope of C1
app.Math.F3.View = True
app.Math.F3.Source1 = "C1"
app.Math.F3.MathMode = "OneOperator"
app.Math.F3.Operator1 = "Envelope"
app.Math.F3.Operat
Example
Sets/Queries the maximum number of sweeps to be used by the envelope function trace Fx.
