| Abstract: | It is introduced that a design idea and method which is applied to portable threephase multifunctional volt -ampere phase meter based on high- powered DSP TMS320LF2407A. This instrument takes DSPTMS320LF2407A as the core processor,uses multi- channel 12 AD7859 carries on data acquisition transforms, may display measurement result with LCD,and may print measurement report. In the article, it is introduced that work principle of instrument and the design of software and hardware. This instrument has many characteristics,for example, the volume is small,the reliability is high, specially precision is very high to the small signal measuring. |
