AbstractThe demands for accurate, phase coherent, data acquisition is increasing with the advances in data analysis and data mining techniques. In addition, the space that data acquisition equipment and its wiring can use is getting smaller as structures become more efficient and space available is absorbed by new capabilities. Thus, there exists a need for instrumentation systems that can be distributed such that it reduces size, wire count, weight and cost. Boeing has developed a feature-rich multi-point transducer bus suitable for highly time deterministic, multiple sample rate, data acquisition systems. The new technology enables the use of emerging high-performance analog and digital signal conditioning integrated circuits into miniature, low-cost modules and smart transducers suitable for flight-test, ground-test, and laboratory applications. This paper explores the development of this technology, the technical challenges it addresses, the benefits the technology brings, and its current applications.
