Usually, there's a VI in the driver called Getting Started. Look for a palette item called Application Examples and see if it's there. Depending on who wrote the driver and when, it might be in a different location. A Getting Started VI is a high level example of using several of the different functions to control an instrument. I would also suggest turning on Show Context Help and as you browse through the driver's palette, you will see descriptions of what each VI does. If you are familiar with the operations of the instrument itself, you'll probably be able to get some clues as to which VIs you need in your application. Any of the VIs you should be able to open and after setting the correct GPIB address, run it and see what they do.
