摘　　要：当今的广播电视技术已经步入数字化、网络化、信息化的时代。在新形势下,发射台站必须结合先进的计算机技术、自动监控技术和网络通信技术,开发及实现中短波发射台的监测系统。调幅度是调幅广播信号的重要参数,是衡量发射机输出功率、能量利用率和覆盖效果的一项重要技术指标,是调幅广播信号质量监测最主要的项目之一,对于调幅广播的安全播出有重要意义。本文对中短波发射台质量保证系统的调幅度测量方法进行研究与探讨。Today＇s radio and TV technology has been entered to the era of digitization, networking, informatization. Under the new situation, the transmitting stations must be combined with advanced computer technology, automatic monitoring technology and network communication technology, the development and realization of monitoring system adapted to the launch pad.？Adjustable amplitude is one of the important parameters for broadcast signal, it also an important technology index for measuring transmitter output power, energy utilization and the cover effect, it＇s important project for monitoring radio signal quality, and it has important significance to safety broadcast. According to the methods of adjustable amplitude measurement of quality assurance system, this paper has carried on the thorough discussion and the research to Medium-wave transmitter quality assurance system.
