YAM机、T特性设备视放板回路的调整和对彩管色平衡的影响

YAM Machine,T Speciality Equipment Inspect Loop Adjusting and Infection of Color-pipe Balance

本文主要讲述了视放回路的原理、调整及其对彩管会聚、色平衡的影响。为解决视放回路过长而引起的视频延迟现象,专门设计了一套视频放大板,其中包括了预视放回路、视频延迟回路、视频放大输出部分及Ek恒压源回路等。

The article mainly introduced the principle and adjustment of video-playing circuit and its influence to color picture tube convergence and color balance. For solving video latency caused by overlong video-playing circuit, a suite of video-magnifying board is specially designed, which includes prevideo-playing circuit, video latency circuit, output segment of video-magnifying and Ek constant voltage source circuit etc.
