I have not been able to use the IVI based instrument drivers for my hp3458. I am still able to talk with with the instument using the low level GPIB functions, but I would like to take advantage of the NI certified drivers for this equipment.
I am using a GPIB-USB-HS controller, Windows XP, and LabVIEW 8.2.
Why haven't you been able to to use the IVI drivers? Do you get an error when you try to use them? If so, what is the error code? If you don't get an error, does it not program the instrument?
There are certified LabVIEW drivers as well. Have you tried those? Unless you really need IVI, I would recomend you use those instead of IVI. I think LabVIEW drivers are a lot simpler to use (and certainly modify). You don't have to do all of the setup in MAX that you need to do with the IVI drivers.
I hope NI is working or has already some LabVIEW certified drivers (not just IVI) IVI is nice when it works but debugging is awful and looking inside impossible.
