AbstractIn 1985 the new Advanced Technologies Testing Aircraft System (ATTAS) will be operable at DFVLR Braunschweig. For this research aircraft a flexible, highly accurate and testable data acquisition system was developed. It consists of a modular and distributed microprocessor system with signal conditioning units situated near the sensors. It is controlled by a master unit with an integrated PCM encoder. The flexible signal conditioning featuring software-controlled parameters and adaptable signal inputs, can be tested automatically via the analog calibration bus using switchable signal paths. The system will be presented in detail and its performance will be shown by typical examples of application within ATTAS.
