Abstract


This paper introduces a system empoldered with SCM technology and virtual instrument technology. Amplitude modulation is a very important technical index, and the conventional measuring method of AM modulation is complex and devoid of the effective interface and cost much more. It is very necessary to empolder a more laconic、flexible、roboticized and extensible AM modulation monitoring system. The system that this paper introduces based on practical application and virtual instrument technology, whose hardware achieves demodulation A/D conversion and connecting with computer; whose software writed with LabVIEW achieves AM modulation monitoring、real-time alarm、teledata issuance、custom setup and so on. This system is not only low cost and using easily, but also, practicable and scalable. With-the computer and broadcasting technology developing, this system will be an effective experiment of the multifunctional virtual instrument’s empoldering in the future.
