The instrument driver for the HP 35670A is only supported under LabVIEW 6 and 7. You should upgrade to the latest version of LabVIEW in order to use the HP 35670A driver or any of the newer drivers that we release in the future.
The instrument driver for the HP 35670A can be found on our web site at http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/61f1c707c2f10906862568ab005fb9ff?OpenDocument.
I hope this helps out.
