What is VXIplug&play?
Hewlett-Packard uses VXIplug&play technology in the HP E1433A. 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.
HP 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
HP E1433A has VXIplug&play drivers for the following frameworks:
Windows 95, Windows NT, and HP-UX.
VXIplug&play drivers
The HP E1433A uses the same drivers as the HP E1432A 16 Channel 51.2
kSa/sec Digitizer plus DSP.
The HP E1432A 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.
