Problems with Agilent 34970A?

[PPLUO]

I want to measure voltage signals.

Now I connect Agilent 34970A with computer through a GPIB-USB cable.
I have installed labview6.0, drivers for the 34970A.
According to the experience in this forum, I select the Ni visa tulip.dll.
But it seems that the computer and the 34970A can not communicate still.
What else can I do?
I am a green hand at hardware. So your suggestion will be appereciated greatly.
Thank you!

PPLUO,

There are really three GPIB-USB devices from National Instruments (assuming that you are not using a third-party GPIB-USB device). The first device, the GPIB-USB, has been obsoleted for newer technology. This obsoleted device can only be run on Windows 98/Me and Windows 95 using version 1.7 of our NI-488.2 driver. The other two devices, the GPIB-USB-A and GPIB-USB-B, will both run on Windows 2000/XP and Windows 98/Me with version 2.2 or 2.3 (2000/XP) of our NI-488.2 driver. 

Now with regards to the tulip.dll driver this is only needed when using HP/Agilent hardware (say an HP PCI-GPIB board). In most cases we want to stick with National Instruments' NI-VISA driver (so I would deselect this DLL when using NI hardware). Version 3.2 is the latest driver for Windows 2000/NT/XP and version 3.0.1 is the latest version for Windows 98/Me support (with version 2.6.1 giving us Windows 95 support). These NI-VISA drivers can be found here:

hi,

use MAX first of all. see your USB GPIB there? your instrument? if not, long way ahead. If yes, you can at least talk to the instrument there.
