Controlling two power supplies using GPIB-USB-HS

[Dennis_Knutson]

Unless you truly need the IVI features, I would recommend the LabVIEW driver. If you don't understand the differences, why did you even select the IVI driver in the first place?

The initialize function of either the LabVIEW or IVI driver creates a reference when called. The resource name by itself is sufficient with the LabVIEW driver and its functions.

The IVI drivers allow me to simulate the power supplies when they are not available.

We do not hava access to the power supplies most of the time.

According with you in an earlier conversation, the IVI drivers are the only ones that allows the simulation.

Which labview driver is the one you recommend ?

The only I found out is not Labview but a third party driver the Agilent 6675A.

The one at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=04709BEF46E04098E0440003BA7CCD... is a native LabVIEW driver. What makes you think it's not?

Go ahead and use the IVI driver, then. Your choice. As I said, the initialize function returns a reference to the instrument session.
