During radio fuze production,signal processor testing was of low efficiency,poor conformance and maintainability by building mixed instrument system.A semi-physical simulation test system of the signal pro-cessor of radio fuze based on PXI-bus was presented in this paper.The system consisted of an embedded real-time PXI control module,a PXI arbitrary waveform generator module,a PXI oscilloscope module,and a PXI programmable power supply module.And the software of the system was designed in the language of Visual C# on the general software programming platform Visual Studio.NET.The PXI arbitrary waveform generator mod-ule generated Doppler signals,which were input the signal processor of radio fuze.The oscilloscope module readout the ignition signal from signal processor,finally,the system output the test result.Analysis of the ex-periment showed the burst height test system based on PXI-bus technology was of high overall performance,lit-tle system error,high efficiency and strong function expansibility.
