摘　　要：依据GB13837标准要求对某视频处理终端进行骚扰功率测试,出现单个频点超标问题,测试不合格。通过分析定位干扰源为机内一块主板上的有源晶振,对该有源晶振电路的匹配电阻电容进行调整优化后,测试通过。According to the requirements of the GB13837 standard,a harassment power test was performed on a video processing terminal,and a single frequency point exceeded the standard and the test was unqualified.By analyzing and locating the interference source as an active crystal oscillator on a motherboard in the machine,the test was passed after adjusting and optimizing the matching resistance and capacitance of the active crystal oscillator circuit.
