摘　　要：针对目前常用信号发生器存在的功能模式固定、价格昂贵、操作不便的缺陷,提出了一种新型多功能的信号发生器,其输出信号的幅值、脉宽、频率、持续时间等均可调,并具有历史数据存储与回放的功能。详细介绍了其工作的基本原理并给出了具体的软硬件实现方法。与同类产品相比,该信号发生器具有功能齐全、操作简便、体积小巧等特点。A new type of multi -performance signal generator is presented for solving the shortcomings of the common signal generator. The amplitude,pulse width, frequency and consistent time can be adjusted and the history data can be storing and read again. The basic principle and concrete designing method of hardware and software are also introduced in detail in this paper. Comparing with other similar products ,this signal generator is characterized with multi -performance,simple -operation and small volume.
