The design of malfunction-measure instrument about broadcasting station

摘要

The paper analyzes electricity signal and main structure about broadcasting station. Basing the systems analysis and the characteristic of measure, the paper presents some testing method about audio-frequency signal, frequency modulation signal. Basing the collectivity design, the paper designs the hardware of testing instrument about broadcasting station testing, adopting VC++ in writing software and adopting the anti-jamming measure. In addition, the paper presents precision-analyzes to realize the measure of failure dot and the precise orientation.
