Abstract:At present, sending and receiving signals in the 1553B bus always relied on special chips, but there were some problems with such implementation scheme, such as unable to verify bus signal or obtain signal distortion, and without enough system expansibility. To solve these problems, this paper chose the combination of FPGA and ADC, DAC, to design a bus signal transceiver and validation module. After experimental verification, the transceiver module designed in this paper could not only realize the reception decoding and sending coding of 1553B bus signal, but also obtain the whole signal waveform to verify whether it meet standard. In addition, this transceiver module had function of generating the distorted waveform, so that laid a foundation for fault simulation. Besides, all the logic functions of this transceiver module were realized by FPGA, it would be easy to upgrade and extend.
