Kevinn,
The first thing you need to do, if you haven't already, is download the instrument driver. This can be found on our web site by going to www.ni.com >> Technical support >> Option 3: Instrument drivers >> downloads >> enter in tektronix, oscilloscope, and LabVIEW. Locate the model number and download and install the driver.
Then, Open, configure and run the example. It's called tkds30xx Getting Started.vi
This should get you started on your way.
