Hey Bethune,
LabVIEW 5.1 is not one of the currently supported versions of LabVIEW and that is the reason we do not have any instrument drivers for the TDS30xx on our web site. New Instrument drivers are only developed for the currently supported version. We recommend that you upgrade to the current version of LabVIEW in order to use the new drivers. For specific instrument driver requests please email technical support.
