What is VXIplug&play?
Agilent uses VXIplug&play technology in the VT1433B. This section outlines
some of the details of VXIplug&play technology.
Overview
The fundamental idea behind VXIplug&play is to provide VXI users with a level
of standardization across different vendors well beyond what the VXI standard
specifications spell out. The VXIplug&play Alliance specifies a set of core
technologies centering on a standard instrument driver technology.
Agilent offers VXIplug&play drivers for VEE-Windows. The VXIplug&play
instrument drivers exist relative to so-called “frameworks”. A framework defines
the environment in which a VXIplug&play driver can operate. The VT1433B has
VXIplug&play drivers for the following frameworks: Windows 95 or later,
Windows NT and HP-UX.
VXIplug&play drivers
The VT1433B VXIplug&play driver is based on the following architecture:
It is most useful to discuss this architecture from the bottom up.
The VISA/VTL I/O interface allows interoperability of the VXIplug&play driver
technology across interfaces.
