LXI Bridge Objective
The main objective behind any bridge or adapter device is to retain all native platform
functionality while providing a transparent path to the protocol or interface of
choice, LXI in this instance. Not only can the design engineer count on the native
performance of the VXIbus, but also leverage the features of LXI such as long communications
path lengths, high data transfer rates, hardware and software independence, and
easy cable routing.
LXI instruments and interfaces have been architected so that hybrid systems can
be easily configured. LAN-based test systems will use standard LAN connectivity
with off-the-shelf switches and hubs permitting simple setup without expensive interface
cards and proprietary cable configurations. Instrumentation can now be placed near
test articles, or where most convenient, without any undue restrictions
using standard copper or fiber optic cable.
Many functional test and data acquisition applications are ideally suited for VXIbus
solutions, and the introduction of a new instrumentation interface will not change
this reality. However, there will be significant opportunities to leverage the advantages
of LXI-based devices, requiring a seamless integration path between the two architectures.
Therefore, bridge devices are essential if the designer hopes to leverage all of
the alternatives available.
