The model you have has a 2GS/s sampling rate and a minimum of 2M sample memory so I don't think 480 hz is going to much of a challenge. I use a lower end model for a higher frequency though much fewer samples and it works fine for me. The best thing to do if you have any questions, is to contact Gage directly. I've found that they're very helpful. They can also provide a LabVIEW SDK. Mine is pretty old - it dates to before their buyout by Tektronix and the subsequent sale from Tek to Kinetic Systems so you should really contact them for current pricing.
