摘　　要：在模拟分量视频信号分析仪器的校准中,现有标准测试信号参数无法根据实际需求进行调整,限制了测量点的选择。为解决这一问题,分析了标准测试信号的参数和测量原理,研究带有失真量的模拟分量视频测试信号,包括:彩条信号、多波群信号、平场信号等。基于SDP2000软件平台、TG700视频信号发生器和VM6000视频信号分析仪器建立实验系统,证明了研究的失真模拟分量视频测试信号可以用于仪器的校准,能够对仪器性能进行全面的评价。In the calibration of analog component video signal analyzer,the existing standard test signals parameters cannot be adjusted according to actual needs,which limits the choice of measurement points.To solve this problem,the parameters and measurement principles of standard test signals are analyzed,and analog component video test signals with distortion are studied,including color bar signal,multi-burst signal,and flat field signal,etc.We established an experimental system with the implementation of the SDP2000 software platform,TG700 video signal generator,and VM6000 video signal analyzer,which proves that the analog component video test signals with the distortion can be used for instrument calibration and performance evaluation.
