Development of the Amplitude-Frequency Characteristic Tester Based on SCM Control

Abstract:

In this paper, the development of the amplitude-frequency characteristic tester based on SCM control has been introduced. The digital frequency synthesizer has been adopted to generate the automatic sweep frequency sine signals so as to provide the reliable sources for the frequency characteristic tester. The amplitude and the frequency characteristics of the active network and the passive network can be obtained through changing the output signals of circuit measuring network by digital analogy as well as the operation program of the microcontroller under the input signals with different frequencies. In this paper, the working principles of tester, the software and hardware design for the frequency synthesizer signals, the hardware and software design of the data collection channels and the applications of LCD technology have been specially discussed.
