本文总结了DVCPRO数字录像机日常维护中设备工作状态和故障隐患的检测技术方法,重点介绍了CTL(控制脉冲)信号和磁鼓RF包络波形两个重要的技术指标信号,通过观察分析记录在磁带上CTL信号和磁鼓RF包络波形判断设备工作状态好坏与否,通过实践证明这是一种很有效和实用的检测设备故障隐患的技术方法,对保障正常节目编辑生产和安全播出具有重要作用。
This article summarizes the DVCPRO digital video recorder routine maintenance of equipment working conditions and hidden trouble detection methods, focusing on the CTL (control pulse) signal and the drum RF envelope waveform of two important technical indicators, through the observation and analysis recorded in the tape On the CTL signal and the drum RF envelope waveform to determine the working conditions of equipment is good or bad, proved by practice that it is a very effective and practical detection of equipment failure hidden technical methods to protect the normal program editing and production safety broadcast Important role.
