I'm using an Agilent 82357A USB/GPIB interface. I can control a LeCroy waverunner scope with simple matlab commands so I assume that the interface is well installed and configured.I also have a LabWindows installation. I tried to use the ivi driver from ni and I have also created a visa session but I couldn't communicate with the scope. I got the message: "The interface is valid but the specified interface number is not configured"So, I'm not sure if I need to do anything special in order to configure the Agilent interface into the LabWindows environment. Any suggestions?Thanks,Andres

LabWindows/CVI

Thanks, I understand a bit better now. I will be returning the Agilent interfaces and buying NI ones.
