| Application of high-performance single chip, especially chips with DSP function andcontinuous enhancement of user's technical requirement have made functions of dataacquisition more and more perfect. The development of single chips and data collectorsat home and that of overseas compared, a kind of vibration test system, based on DSP, isresearched. And the functions data acquisition and display of vibration signal isvalidated in practice, high-speed data collection and USB interface technology are thecharacteristics. The structures and characteristics of this vibration signal gather system areintroduced in detail in this paper.
