Hi,
You first need to be able to communicate with your instrument in MAX (under Devices and Interfaces) before you start using the instrument driver in LabVIEW. Once you establish communication with the instrument in MAX, use the same resource name (GPIB::your instrument's GPIB address::INSTR) in LabVIEW. You mentioned that the instrument you are using is Agilent 34970A but the screenshots show that you are trying to use a driver for a different instrument (HP34401A). Please make sure to download the correct driver from ni.com/idnet.
Regards,
Vesna
