摘要 在EMC微波暗室利用高精度示波器和频谱仪对计算机工作时显卡产生的辐射信号进行测试,获得时域和频域的数据,进行相应的分析,对测量数据进行特征提取和分析对比,研究计算机显卡信息泄漏的特点,为进一步的特征库建立和信息复现提供帮助。 We use high accuracy oscilloscope and spectrum analyzer on the computer graphics when the radiation signal test in EMC microwave anechoic chamber,meanwhile,obtained and analysis the time domain and frequency domain data. Study the computer information leakage characteristics for the further characteristic database establishment and information reproduction
