I have several questions concerning a GPIB  LabVIEW driver for the power analyzer NORMA 5155 (NORMA is now part of LEM company):  
1- Has anybody programmed a driver specially for this device so far ? 
2- Is it possible to use other similar drivers (LEM/NORMA 4000..6000) for it? 
3- How would you approach building a suitable driver? (Instrument I-O Assistent ...,)? 
Any answer  could be helpful.
