I'm hooked up to a HP 54120A and I can't seem to connect to it. I have sent it simple VISA-based queries and they all get timed out. Max sees it as GPIB0::7 and I can select it as a device ID in LabVIEW. But I can't get it to listen or talk to me. Someone I talked to on the phone suggested that I toggle the TALK/LISTEN mode on the front panel. All I can see is a LOCAL button and nothing happens when I press it. I have a program that I wrote a year ago and it worked back then. But someone else was playing with the buttons on the scope back then and he's not here any more.
