I'm using LabView 2012 student version in OSX 10.8.2. I already downloaded the driver from NI website. I pressed the run in the virtual interface, but didn't see any actions. Is there anything that I should check / initialize before I use the virtual interface? I attach the interface that I see from the screen. Thanks very much.
After looking into the HP 3478A.vi, it appears a default GPIB address of 23 is used in the VI so if that is not the address of the connected DMM then you would not see any measurements. Below is a link to a Knowledge Base that shows how to find the GPIB address of listeners on your computer.
