In view of design complexity and long development cycle for traditional pseudo-random code, it is intended to design a multilevel BPSK modulation pseudo-random code waveform generation system. Based on deep analysis of generation principle and performance features, it executes system design by application of PXI module, LabVIEW software and VI toolkit. The results show that this system is equipped with strong flexibility and extendibility that can demonstrate the generation of pseudo-random code and validation for anti-interference performance of fuse.
