The development of single chips and analyzers at home and that of overseas compared , a kind of pocketable dual - channel and multi - function signal analyzer , based on dsp , are researched with the functions of dynamic analyzer , data logging acquisitor , start - up / coast - down analyzer and dynamic balancer , etc . and the functions data acquisition , storage , display and analysis of vibration signal are validated in practice , high - speed float point data calculation ability , large memory space and simple operation are the characteristics 高性能单片机尤其是dsp功能芯片的采用及用户技术要求的不断提高，使得信号分析仪的功能越来越完善，在比较了国内外单片机和信号分析仪的发展现状后，开发研制了一种基于浮点dsp芯片tms320c32的便携式双通道多功能信号分析仪，兼有动态信号分析仪、巡检数采器、起停车分析仪、动平衡仪等多种仪器的功能。
