| Abstract: | A data acquisition and analysis instrument using ARM7TDMI embedded architecture is introduced.Implementation of virtual instruments based on embedded system is made possible by ARM7,which is much more powerful than MCU.Single channel 200kSps sampling,synchronous waveform display and two novel triggering modes catering to rotary machine vibration analysis are realized herein.Implementing uC/OS II as the operating system,the speed of connection with PC can reach as high as 1 Mbyteps via USB. |
