摘要
为满足生产和科研的需要,研制了一种用Altera公司MAX7000系列CPLD芯片,实现的程控脉冲信号源。实践证明,应用此种方案设计的信号源,频率高、频率稳定、步进小(通过选用高速CPLD可提高频率及缩小步进)、精度高、参数调节方便,同时操作简单方便,功能更易扩展。文中给出了该信号源的详细系统设计方法及程序源代码。
To meet the need of production and scientific research, we have developed a pulse signal source with program control based on the CPLD chip of Ahem company MAX7000 series. Results show that the signal source designed by this scheme has the advantages of high and stable frequency, small step (by choosing high speed CPLD frequency can be increased and step can be reduced), high precision, easy adjustment of parameters, easy operation and expandable function. This paper presents a detailed system design of the signal and the code of the program source.
