摘　　要：在矢量网络分析仪的基础上设计了无源互调测量系统。该系统由矢量网络分析仪与双工器、合路器等无源器件组成,由矢量网络分析仪提供两个源与接收机功能,并将功率放大器、双工器、合路器等集成测试装置。在此基础上,设计并搭建了互调测量系统,实验测试表明:自身互调测量达到≤-168 dBc@2×43 dBm,测试结果与标准件基本一致,其测量误差分别为0.35%,0.64%。该系统具有很高的测量精度,既可测量无源互调,又具有矢量网络分析仪的功能,并且在系统集成上具有良好的适用性,有效地拓展了矢量网络分析仪的测试功能。Passive inter-modulation measurement system is designed based on vector network analyzer,which consists of a vector network analyzer and passive components such as diplexers and combiners,provids two source and the receiver function,and integrates the power amplifier,duplexer,combiner into testing device.Inter-modulation measurement system is designed and built,the experimental results show that inter-modulation itself measurement reaches≤-168 dBc@2×43 dBm.Test results are basically identical with the standard parts,but existing measurement error of 0.35%,0.64%.The system has high measurement accuracy,not only measures the passive inter-modulation,but also has the function of a vector network analyzer,and has good applicability in the system integration,effectively expands the vector network analyzer test function.
