Analog standard source with IEC61850 digital interface and testing method thereof

The invention discloses an analog standard source with an IEC61850 digital interface, wherein the analog standard source comprises an RAM storage unit, an IEC61850 processing unit, an Ethernet interface, a D/A converter, an amplifier unit, a communication control unit, a man-machine interaction unit, a DSP processing unit and a pulse transceiver module. According to the analog standard source with the IEC61850 digital interface and the testing method thereof, 50000 points in each frequency can be realized; high filtering effect can be realized through a self distributed capacitance; and high accuracy and high reliability of the analog standard source are ensured. The analog standard source with the digital interface realizes output of a digital standard power source through performing homologous extraction on the fitting points in each frequency. 本发明公开了种带有IEC61850数字接口的模拟标准源，包括：RAM存储单元、IEC61850处理单元、以太网接口、D/A转换器、放大器单元、通信控制单元、人机交互单元、DSP处理单元、脉冲收发模块。本发明提供的种带有IEC61850数字接口的模拟标准源及其检测方法，能实现每周波50000点，通过自身分布电容即可达到好的滤波效果
