Hi,
Currently there is no support for analyzer functionality in win2000. We are currently workig on the new driver which will make all of your requests possible. I cannot give you a release date, but I can tell you that we are working hard to get this driver completed. If you would like to become part of our beta program, create an email service request at www.ni.com/ask, make the question type gpib, and in the subject put my name "Aaron K." somewhere in the subject line.
Hope this helps out!
Best Regards,
Aaron K.
