What is it that you're trying to do? Get drivers for the instrument, or do you want to know how to use the instrument? For the latter, the obvious question is: do you have the manual? If not, you can get it from the Agilent web site. For drivers, you can find a LabWindows/CVI driver from
Agilent. It contains a .fp (front panel) file that you can use to create LabVIEW wrapper VIs so you can call the drivers from LabVIEW.
