An Integrated Telemetry Decommutation and Display System

Abstract

This paper describes an integrated architecture providing in a single box the complete functions of a telemetry system. The 3700 Decommutator can perform data synchronization, tagging and merging, as well as processing and output in various forms, on different input streams simultaneously. Most functions of larger telemetry systems are implemented here at the card level. Being based on a VME bus architecture, the unit is very modular and can be configured differently according to the specific requirements of particular test programs. The 3700 Decommutator can be used as a stand-alone station, providing Aquick-look@ monitoring of real time data to different independent users, or as a computer front-end in a larger system. It is a compact unit, easily transportable. Front-end functions and product features are presented, illustrating the large number of applications of the unit. The variety of display formats that can be created and rapidly modified by users is described. Flexibility in set-up and operation is then discussed, in order to demonstrate how a simple database structure matches a modular hardware architecture, resulting in a userfriendly unit allowing rapid and easy changes in mission set-up.
