摘要
系统设计了以Maxim公司生产的MAX038信号发生芯片和美国Atmel公司生产的AT89S52单片机作为核心的信号发生器,利用AT89S52单片机的智能控制功能,实现对信号产生芯片MAX038器件的控制,产生不同频率的三角波、正弦波、和方波等信号波形,波形输出可以通过键盘输入进行选择,波形的频率可以通过电位器进行调节,同时在LED上显示出来,设计的信号发生器结构简单,不需要调整,具有很高的性价比,频率从几个赫兹到几十兆赫,除了供通信,仪表和自动控制系统测试用外,还可广泛用于其他非电测量领域。
The system designs the MAX038 signal generator which produced by Maxim Corporation, with the chip by American Atmel Corporation produced to take the core the signal generating device, used at89S52 monolithic integrated circuit's intelligent control function, has the chip MAX038 signal generator under control, had the different frequency triangular wave, the sine wave, and the square-wave equisignal profile, the profile output may carry on the choice through the keyboard entry, the profile frequency may carry on the adjustment through the potentiometer, simultaneously on LED demonstrated that the design signal generating device structure was simple, did not need to adjust, has the very high performance-to-price ratio, the frequency from several hertz to several dozens of megacycles, besides supplied the correspondence, the measuring appliance and the automatic control system test with, but may also widely used in other non-electric survey domain.
