摘要
稳相电缆的弯曲相位稳定性指标对于相敏系统中的信号传输而言至关重要。为了精确测得电缆弯曲前后相位的变化量,本文介绍三种电缆弯曲相位稳定性的测试方法,并通过实例的测试对其进行比较和分析。
For signal transmission in phase-sensitive electronic system,it is very important to ensure the phase stability index with bending of phase-stable coaxial cable.In order to accurately measure the phase change of cable before and after bending,three test methods for measuring phase stability with bending were introduced,and the test cases were discussed and compared.
