Application of Pulse Code Modulation (PCM) Technology to Aircraft Dynamics Data Acquisition.

Abstract

AFWAL/FIBG has a facility that provides dynamics data acquisition and analysis to support ground and flight testing on Air Force systems. This capability is limited by the current analog data acquisition technology to the acquisition of 12 data channels simultaneously of 40 to 50 dB dynamic range. This report documents a study conducted to obtain an optimum data acquisition and analysis system using PCM technology to provide simultaneous acquisition of 144 channels with 60 to 70 dB dynamic range. Implementation of this design will advance the state-of-the-art for acquisition of high bandwidth (20 KHz) dynamics data and will result in a significant reduction in the cost of flight tests.
