摘要
随着计算机技术和网络技术的发展，自动控制技术在广播电视发射台已经得到了广泛的应用，但发射机指标测试依然延续着传统的手工操作方式，使用专业的仪器仪表实现指标测试，测试前期的准备工作多，完成测试的时间较长，发射机在线指标检测系统的提出是对传统的指标测试的巨大改进，通过对其测试原理的进行深入分析对比，针对在线检测测试的特点进行应用分析，在此基础上挖掘该系统在检测广播发射机的应用价值。
With the development of computer technology and network technology, automatic control tech- nology in radio and television transmission has been widely used, but the transmitter test is still a continuation of the traditional manual mode of operation, to achieve test instruments of professional testing, pre- paratory work, complete the test time is longer, this online detection system transmitter the index is a great improvement on the traditional index test,in -depth analysis by comparing the testing principle, application analysis according to the characteristics of online testing, mining application value of the system in the detection of radio transmitter based on.
