数字调幅发射机天调网络的调试

Adjustment and Test of Antenna Tuning Network for DAM Transmitter

随着数字技术的发展,中波数字调幅(DAM)发射机由于技术先进,在广播发射台推广应用很快。天线调配网络的调试是DAM发射机安装调试中的重点。本文着重探讨了DAM发射机对天调网络的要求及网络的实际调试,并在实际调试中总结了一些经验。

With the development of digital technology, MW digital amplitude modulation(DAM) transmitter is rapidly disseminated and applied at broadcast stations becauseof its advanced technology. The adjustment and test of the antenna tuning networkare the priorities of the installation and tuning of DAM transmitter. A special effort ismade to approach the requirements for DAM transmitters antenna tuning networkand its practical adjustment and test and some experience in the adjustment andtest is summed up.
