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. Andreas, Germany"
