摘　　要：介绍一种宽带数字功率计，采用数字采样实时处理方式，显示三相电压、电流、功率、功率因数，实现Ａ、Ｂ、Ｃ三相电压、电流波形采集、显示和频谱分析。A wide-band digital power meter is introduced.The meter can real-time acquire three-phase voltage/current samples and calculate power,which measured as factor as RMS/MEAN value for voltage and current.Then it display them on LED at its panel. These samples can be transfered to a PC via serial port to get spectrum analysis.
