Hi,
I was able to find a driver for the Marconi instrument at www.ni.com/idnet, but unfortunatly not the advantest hardware.
An instrument driver is a collection of functions that implement the commands necessary to perform the instrument�s operations. In short, someone read the instrument user manual and implemented some of the functionality in a program for the end user. Instrument drivers are not necessary to use your instrument. They are merely time savers to help you develop your project so you do not need to study the manual before writing a program. You should be able to get the functionality you require, relatively quickly by using an example.
There are example VI's in LV on Instrument Connectivity. If you go to the Help menu >> Examples.. >> I/O
, you will see a couple and Examples.. >> Fundamentals for File and String manipulation. I would suggest tweaking them to suit your application. Also the specific command that your instrument responds to can be found from it's manual.
Some useful resources for your application are
ni.com > NI Developer Zone > Development Library > Instrument Connectivity
http://search.ni.com/?col=alldocs&layout=TechResources&ql=a , to search examples and knowledge bases
Hope this helps!
