This paper designs a multi-purpose excitation signal generation module for avionics testing based on the radio frequency agile transceiver and field programming gate array architecture.The design method of software defined radio and online reconstruction of digital logic functions are adopted to generate test excitation signals with different frequencies,powers,and modulation types,achieving functional and indicator testing of airborne communication,navigation,and identification equipment.Compared with traditional excitation generation architectures,this design can achieve single board fusion of multiple test excitation signals over a wide frequency range.It has the advantages of low cost,low power consumption,compact structure and scalability.It has broad application prospects.
