EXAMPLE IN VBA
VBA is the programming language built in to many of the more recent Windows applications. It is a subset of
Visual Basic that makes using OLE Automation Servers and ActiveX Controls very simple. The following VBA
subroutine demonstrates how easy it is to connect to an X-Stream DSO and send remote commands to it.

Call dso.WriteString("DISP ON", 1) Enable the internal display routine
Call dso.WriteString("TRMD AUTO", 1) Set the trigger mode to AUTO
End Sub
