摘要 同频信号之间的相位差测试是电子测量和信号检测处理的重要内容,在许多领域有着广泛的应用。针对通用检测设备宽范围以及高精度的要求,介绍了一种基于单片集成电路AD8302的接收机相位差测试系统,采用PC104总线结构,具有体积小、结构简单、测量频率范围宽、通用性好等优点,可以用于便携式检测设备中。基于所述方案的相位差测试系统,已经在“便携式雷达性能综合测试仪”实际应用中得到了验证。 The test of phase-difference between same-frequency signals is important to electronic measurement and signal detection, and has been used in many fields. For the requirement of wide testing range and high accuracy in universal testing equipments, this paper introduces a receiver phase-difference testing system based on AD8302, which uses PC104 bus, small in dimension and simple in structure. It provides a wide range of frequency and a good communality in test. This system has been verified in the actual application of the "portable radar performance testing instrument".
