摘　　要：混频器的传统测试是由信号源、频谱仪或者功率计进行的,其测试效率低,并且不能对变频增益的相位进行测试。文中介绍了基于矢量网络分析仪的混频器的自动化测试,采用了GPIB接口技术和LabVIEW编程,设计并搭建了硬件测试平台,实现了对混频器的输入回波损耗、相对变频增益和相位的测试。该测试平台测试精度和效率高,在实际应用中取得了良好的效果。The traditional test method of mixer was tested by the signal source, the frequency spectrum instrument or the power meter, meanwhile, conversion gain phase can not be tested. This paper introduced the automated testing of the mixer based on vector network analyzer, GPIB interface technology and the LabVIEW programming were used, and the hardware test platform was designed and built, realizing the test of mixer input return loss, relative conversion gain and phase. The test platform is accurate and cefficient, and it achieves good results in practical application.
