ViFind32
A console application that uses the viFindRsrc and
viFindNext VISA functions to enumerate all resources
visible to VISA. This application is useful for verifying
that all expected interfaces have been configured by
Connection Expert, and that the expected devices have
been attached. ViFind32 is part of the Agilent IO Libraries
Suite.
virtual instrument
A name given to the grouping of software modules (such
as VISA resources with any associated or required
hardware) to give them the functionality of a traditional
stand- alone instrument. Within VISA, a virtual instrument
is the logical grouping of any of the VISA resources. The
VISA Instrument Control Resources Organizer serves as a
means to group any number of any type of VISA
Instrument Control Resources within a VISA system.
VISA
Virtual Instrument Software Architecture. VISA is a
standard I/O library that allows software from different
vendors to run together on the same platform. Agilent
VISA is part of the Agilent IO Libraries Suite.
VISA address
A resource descriptor that can be used to open a VISA
session.
VISA alias
A string that can be used instead of a resource descriptor
in VISA programs. Using VISA aliases rather than
hard- coded resource descriptors makes your programs
more portable. You can define VISA aliases for your
instruments in Connection Expert.
