摘要
介绍了实际工程中常用的射频线缆损耗的测量方法——直接读值法和插入损耗法,通过实际测试,对比了这两种方法的优劣及特点,重点针对同步参考频率和不同步参考频率的测量结果进行了分析,给出了选择测试方法上的建议。
Two methods in measurement of cable loss, direct measurement and insertion loss measurement, are described. The advantages and disadvantages are illustrated according to test results. Especially, the measurement results under the condition synchronization and non-synchronization are analyzed. Some suggestions are proposed refer to choice measurement methods.
