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.
