新型字符叠加平板显示CATV电平表

The realization of new pattern OSD Flat Panel Display CATV Level mete

文中介绍了一种用于测量CATV前端系统输出口射频信号电平值的仪器。它是以纯数字化FPD作为显示终端,在FPD屏上能够通过OSD技术同时显示视频图像与被测信号的各项指标值。

In this paper a new pattern CATV mete that can measure the output level of RF signal is introduced. It uses pure digital Flat Panel Display as display terminal. Video and each measured index value can be displayed at Flat Panel Display simultaneously.
