摘　　要：介绍了一种综合采用频率合成和模拟扫频技术的微波合成扫源的设计方法及实现,给出了微波信号发生器的原理,叙述了基于嵌入式Linux的软件系统的开发。测试结果显示:该仪器的频率切换时间为45ms,单边带相位噪声为-75dBc/Hz,功率准确度为0.52dB。采用基于嵌入式Linux平台上的Qt/Embedded编程具有界面友好、开发速度快、系统小巧等优点。A type of microwave signal generator is presented which combines frequency composite technology and analog scan frequency technology. The principle of microwave signal generator is introduced and the design of embedded system based on Embedded Linux is described in detail. A test of the product indicated that its frequency switching time is 45 ms,single sideband phase noise is -75 dBc/Hz, power accuracy is 0. 52 dB. It is of advantage to better user interface, more quickly programming and smaller code and so on, that programming with Qt/Embedded based on Embedded Linux.
