摘要
设计了一种电视用Tuner(电子调谐器)调试评价系统,该系统能够对数模一体Tuner单品进行性能调试和评价,其核心硬件是Tuner测试夹具和视频解码回路。测试时只需将Tuner安置于夹具上,并依次与控制PC、视频解码回路、显示器等设备相连接,待系统上电运行稳定后,即可通过安装于PC中的应用程序进行测试。本系统操作简单、携带方便、结果准确,不但适用于实验室环境,同时也可满足户外复杂现地信号的测试。
A digital/analog TV tuner adjustment and evaluation system is designed. The system can adjust and evaluate signal product of tuner. The important hardware is tuner test jig and video decoder circuit. If tuner sample need be tested, just put it on jig and connect with PC, video decoder circuit and monitor. When the PC run steadily, users can examine the applied program erected. The system is easily to be operated and carried. The system result is exact. This system not only can be used in laboratory, but also meet the demands of local complex outside signal.
