      Modern aircraft now employ widely accepted and standardized technology commonly found in COTS applications. One such technology, Fibre Channel, has been deployed to transport both low and high-speed measurement data. Data as varied as “command and control”, “Radar Sensors” and “video” are being transmitted over fibre channel on many aircrafts. Some of these applications require data monitoring in listening mode only where transmission from the instrumentation equipment is not allowed or possible. As a result, standard off the shelf Fibre Channel devices cannot be used, and a development of a general purpose Fibre Channel monitor/ analyzer device and product is required. This paper discusses the concept, merits, and implementation of fibre channel bus monitoring in modern data acquisition systems. Techniques for tapping into an optical fibre channel network, as well as, a recording format for IRIG106 Chapter 10 are included. An overview of fibre channel topologies and protocols is also provided.

      Many engineers express frustration with the multitude of vendor specific tools required to describe measurements and configure data acquisition systems. In general, tools are incompatible between vendors, forcing the engineer to enter the same or similar data multiple times. With the emergence of XML technologies, user centric data modeling for the flight test community is now possible. With this new class of technology, a vendor neutral, standard language to define measurements and configure systems may finally be realized. However, the allure of such a universal language can easily become too abstract, making it untenable for hardware configuration and resulting in a low vendor adoption rate. Conversely, a language that caters too much to vendor specific configuration will defeat its purpose. Achieving this careful balance is not trivial, but is possible. Doing so will produce a useful standard without putting it out of the reach of equipment vendors. This paper discusses the concept, merits, and possible solutions for a standard measurement metadata model. Practical solutions using XML and related technologies are discussed.
