Design of Instrument Control System Based on LabView

Frequency meter, power meter and spectrum analyzer are necessary testing equipments of digital terrestrial television broadcasting exciter testing. In this paper, a virtual instrument technology based on Lab View is proposed to control automatically testing equipments. Using the instrument control reading technology, we can realize the function of saving the original text files and the image files of master interface. The application of Academy of Broadcasting Science SARFT shows that the design has the convenient and practical advantages, as well as a strong promotional.
