Hi Mohan,
Unfortunately there isn't a instrument driver specific to that device. What you could do though is use our NI-VISA driver and try to communicate with the instrument over serial (I assume it uses serial for communication) There are examples in the Example Finder (Help>>Find Examples) that ships with LabVIEW that will demonstrate some functions you can use. I hope this helps out.
