viPrintf(vi,":POW?\")   from agilent

Firstly, if instrument which you're using can be drived by NI VISA or Agilent VISA, you can use any one to program. Also the difference between these two functions are inherent for being defined by drivers.

Secondly, once in the same computer, I suggest that you'd better use only one driver to avoid conflicts or some else problem.
