You might be able to improve on the 1 second update rate. It would help if you post the program you've written. However, you are never going to get 'real-time' with GPIB. It's not so much a limitation of the driver as a limitation of GPIB. You've got a max transfer rate of 1MB/sec with GPIB and in practice, it's much less than that. The instrument and interface ared not designed to simultaneously capture and transfer. If you really continuous monitoring in 'real-time', you would be better off using a pc based scope card. Otherwise, as I mentioned earlier, post an example of your code to see where it might be optimized.
