NI-VISATM FOR WINDOWS NT/95/98:
WINNT, GWINNT, WIN95, AND
NI-VISA is a standard I/O Application Programming Interface (API) for
NI-VISA can control VXI/VME, PXI, GPIB, or Serial instruments, making
the appropriate driver calls depending on the type of instrument being used.
NI-VISA uses the same operations to communicate with instruments
regardless of the interface type. For example, the NI-VISA command to
write an ASCII string to a message-based instrument is the same whether
the instrument is Serial, GPIB, or VXI. As a result, NI-VISA gives you
interface independence. This makes it easier to switch bus interfaces and
means that users who must program instruments for multiple interfaces
need learn only one API.
Another advantage of NI-VISA is that it is an object-oriented API that will
easily adapt to new instrumentation interfaces as they evolve, making
application migration to the new interfaces easy.
VISA is the industry standard for developing instrument drivers. Most
current drivers written by National Instruments use NI-VISA and support
Windows NT/95/98, Solaris 2, HP-UX, VxWorks, and Macintosh, as long
as the appropriate system-level drivers are available for that platform.
