You can use either the VISA functions or IVI or GPIB (IEEE 488.2). - VISA functions are low-level functions for Serial, LPT and GPIB communications. - IVI are generic drivers for all kind of instruments. - GPIB are interface specific and enables you for example to use the SRQ line in order not to take too much resource on your computer...
The instrument driver that you can download with the link I've send is probably the best thing to use if you're not familiar with this kind of communications ! That's all I can do from here. Hope this helps ! Greets, Julien
