基于FPGA的信号发生器在分频器检测上的应用

Application of Signal Generator in Detecting Frequency Divider Based on FPGA

根据直接数字频率合成技术,以MSP430作为控制系统控制正弦波的频率,FPGA系统作为核心设计了一台信号发生器,产生在0 ～9 999Hz频段范围内频率可选的正弦波信号,解决了运载火箭分频器的检测中多台分频器不能同时进行高/低温试验,影响生产效率的问题.正弦波信号波形光滑,失真度小,可同时供给8台分频器,极大地提高了生产效率.

Based on the technology for direct digital frequency synthesis,MSP430 control system was used to select sine wave＇ s frequency and FPGA-cored signal generator was designed to produce sine wave＇ s signal with 0 - 9 999Hz selectable frequencies so that the matters influencing production efficiency caused by many frequency dividers which failed to implement high and low temperature tests at the same time while detecting rocket launcher＇ s frequency divider can be solved. The sine wave signal which boasting of smooth waves and low distortion can be provided to eight frequency dividers to improve production efficiency greatly.
