A New Way of Generating Actuating Signals for Fuze Board

Abstract

In order to completely test the working conditions of fuze board in some type, an actuating signal with adjustable frequency and amplitude is needed. This paper shows a new idea which is based on DSP+FPGA+RAM+D/A to generate the signal, that can be explain as: the arbitrary waveform sampling data are transmitted from the PC to DSP through COM, then to RAM after being calculated and processed by DSP, FPGA controls the schedule of RAM to put the recovering wave out. The length and the number of waveform are being controlled. The waveform is arbitrary and the operation is flexible. The experiment shows that to actuate signal by this method is more flexible compared to the traditional DDS way, and it may be used in fuze circuit test much better and reduces the cost a lot. Thus it's strongly practical and promotional.
