To meet the demand of avionics control system's frequency response characteristic and the testing, a new avionics frequency response testing system is proposed. The design uses PXI series card of NI Corporation and the software programming is used in the design, to realize the function of the testing signal's generation, the collection of the response signal, the processing of the sampling data and the mapping of the system's frequency response characteristic curve, and so on. In this paper, the hardware composition, software design, testing steps, and the processing method of data sampling are mainly introduced. The results of application show that the proposed system is economical and reliable. It has a good stability and can meet the avionics system frequency response testing requirements. It not only achieves all the collection of the response signal, analysis and calculation, but also achieves the data storage and playback. The proposed system has the advantages of simple and quick, flexible configuration, portable, low cost, and so on.
