摘　　要：设计了一款基于Visual Studio的多通道相参接收机测试系统。该系统由是德科技有限公司的模块化设备构成,包括数字采集接收机M9703A、信号源M9380A(由源输出M9301A、锁相环M9310A、频率参考M9300A组成)、4路下变频器M9362A、IF(intermediate frequency,IF)放大/衰减器M9352A及功率计N1911A等。通过程序设计,实现PC(personal computer,PC)端对其进行指令控制。该系统使得测试过程简捷,可完成多达16通道的相参测试。整套系统在使用中性能良好、稳定性强,该系统测试幅度误差在小于0.1dB,相位误差小于1°。A multi-channe2 coherent receiver testing system has been designed, which based on the Visual Studio. It con- sists of the modules which are provided by the Keysight Technologies CO. , LTD, including digital receiver M9703A, signal source M9380A （made of the source output M9301A, phase-locked loop M9310A and frequency reference M9300A）, Quaddown-converter M9362A, IF Amplifier/AttenuatorM9352A and Power metersM1911A. The sys- tem can he controlled on PC by program designing, and it makes the measurement convenient finish sixteen coherent channels testing. The system is stable and performing well, the amplitude error is less than 0.1 dB, the phase error is less than 1 degree.
