The right hand column shows the possible arguments. The context of each of the automation commands used above can be found using the XStream Browser or from the Automation Command Manual:ДЇigure 3 shows the XStream Browser with the Cursor Type command highlighted. Save the script using any name with a LeCroy Setup Script.lss file extension. Open Notepad and copy the script into Notepad. If the cursor is turned off exit the While loop, clear the вЂscript runningвЂ™ messageДisplay a message that the script is complete. Loop back to the start of the While loop. Pass the horizontal cursor location to the zoom center location. Start a While Loop to run until the cursor is turned off. Zoom trace Z1 is set to a 10:1 horizontal expansion and turned on. Set the cursor type to Horizontal Absolute and turn it on Set app = Nothing Description of the steps in the scriptДЇirst we use the creatobject statement to link to the scope using the variable вЂњappвЂќ.Дisplay a message that a script is running. 'set arguments to 0,False to wait for a triggerable event.

Here is the script created in the NotePad Windows application: set app = CreateObject('LeCroy.XStreamDSO')ДЄpp.SystemControl.PersistentMessage = 'Script running turn off cursor to stop.' So as you move the cursor the zoom trace will follow the cursor location. LetвЂ™s start by creating a Visual Basic script that will use the horizontal absolute cursor location to control the center location of a zoom trace. We will use a similar approach in developing a Visual Basic script to automate the scope operation. CreateObject returns a handle to us, which we store in the XStreamDSO variable. Once it has instantiated (connected to) our DSO application we need some kind of вЂhandleвЂ™ (pointer) to it so that we can use it later to communicate with the instrument. The argument вЂњLeCroy.XStreamDSOвЂќ refers to our DSO application. Set XStreamDSO = CreateObject('LeCroy.XStreamDSO')Д¬reateObject is the Visual Basic function that creates an instance of a COM Server (a.k.a.

The XStream browser introduction can be found in the remote manual on page 72 and in the Automation Manual on page 1-5. (This is a nice way to find and test commands). It will let you make changes to the scope from it and you can also make a change on the scope and then refresh the browser to read the new value. This application connects to the scope and exposes the automation items. Among the topics discussed is the use of the XStream Browser. This manual is a comprehensive resource on all the aspects of automation programming. Users are strongly urged to consult LeCroyвЂ™s Automation manual on the LeCroy Website at:

It doesnвЂ™t rely upon any third-party development tools, since it uses WindowsвЂ™ built-in text editor (Notepad) and the Visual Basic Script interpreter (VBScript), which is also installed on all LeCroy XSream oscillocopes.

#VISUAL BASIC SCRIPT HOW TO#

This tutorial presents a procedure of how to create a simple remote control application, which will run on the instrument, from scratch. In effect, each time a panel is saved, the instrument effectively writes you a program that, when executed, returns the instrument to the saved state. Scope setup files, in X-Stream DSOs, are ASCII text files that contain a complete Visual Basic Script вЂњprogramвЂќ that, when вЂњexecuted,вЂќ will restore the instrument to a previously recorded state. Using COM, the controlling application can run directly on the instrument without requiring an external controller. In addition to supporting the familiar ASCII-based remote commands that have been used to control all LeCroy DSOs for many years, all of the Windows-based вЂњX-StreamвЂќ instruments fully support control by Automation interfaces based on MicrosoftвЂ™s Component Object Model (COM).
