Hi,
I'm not sure what question you are asking. You can directly access the device using the GPIB command in Instrument Control, or via a VISA driver using the VISA command. The toolbox ships with a driver for Tek scopes that will most likely work with your device, and allow you to use properties and methods, rather than SCPI style commands.
