摘　　要：利用频谱分析仪对计算机输入设备工作时发射的辐射信号进行测试,获取输入设备辐射信号的频谱数据并进行相应的频谱特性分析。找出其泄漏的主要频段和特点,为输入设备的防护提供依据。Using the spectrum analyzer we can test the radiated signal emitted by the computer input device when they are working, and obtain the spectrum data of the radiated signal in order to analyze the frequency chart characteristic. From the data, we are able to find out the main frequency range and the feature leaked by the input device, so as to offer the basis for protecting the input device.

关 键 词：计算机输入设备 辐射信号 频谱特性
