描述
在彩色电视白场测试领域,通常采用由与图1色度变换(I/V)构成集成化探头,而将A/D变换与色度计算等工作交给PC机处理,例如美国Klein公司的K5/10系列。利用PC软件技术,K5/10系列增加了频谱分析功能,可以分析O~100Hz内的电视及计算机显示器的“闪烁”,是CAl00/200系列所不能完成的。
在本文的工作中,笔者设计制作了CSE808新型的彩色分析虚拟仪器,特点在于将虚拟仪器的概念扩展到通信系统层的资源共享。采用ARM7TDMI内核的三星4510B硬件通信系统以及Vxworks嵌入式软件实时操作系统,实现了3路16位并行20kHz采样率的光度色度数据采集,并采用100M以太网和TCP/IP协议传输数据,领先于美国Klein公司的K5/10系列彩色分析仪。预计该系统在“刷新频率”、“响应时间”等与显示器相关的瞬态光度色度计量测试领域具有重要意义,在航空闪光警示灯质量检定领域也具有重要应用价值。
