DSP APPLICATION TO THE PORTABLE VIBRATION EXCITER

摘要

In the paper a new portable battery operated exciter dedicated for the calibration of the mechanical vibration sensors (transducers) is presented. This instrument is based on the Motorola's digital signal processor DSP 56167 which is quite new approach to the construction of such instrument. The DSP with the reference sensor used as an information source about the generated vibration signals constitutes the measurement system. This system is used for the generation of the reference mechanical vibrations. The digital approach to the calibration ensures the new level of the performances. Programmability of the generated vibration amplitude, frequency accuracy and the level of total harmonic distortions (THD) overcomes all other designs available on the market.
