A MULTIPLEXER/RECORDER ARCHITECTURE FOR USE WITH CONVENTIONAL MEDIA TECHNOLOGY

Abstract

Instrumentation recorders have evolved continuously over the years. Their growth has primarily been driven by technology advancements. The latest recording equipment generally utilizes hard disk, disk array, or solid-state storage technology, which results in greater capacity and performance. Most recorders integrate storage media with multiplexer electronics resulting in a highly efficient yet inflexible and physically large recording system. This paper describes an instrumentation multiplexer/recorder system using an open architecture between the multiplexer and the storage media that allows insertion of conventional recording technologies. This approach provides a generalized solution with enough flexibility and scalability to address the majority of instrumentation recording needs. This system is based on the latest IRIG-106 chapter 10 standard, thus supporting interoperability throughout the flight test community.
