Hello,
The best two places to look for instrument drivers are ni.com\idnet and the instrument manufacturer. If you do not find it there, NI does develop drivers internally of course, and if not already under development, you can suggest as much by emailing instrument.drivers@ni.com. There is of course no guarantee that the driver will be developed, but you should be able to get feedback on the matter. One issue which prevents driver development is availability of the instrument, which often times is not purchases, but rather received on a loan basis for the development period.
Repost with an update or any other questions!
Best Regards,
JLS
