Test method for coaxial cable structural return loss
同轴电缆结构回波损耗试验方法
With the increasing of digital cable transmission frequency , srl ( structural return loss ) on - line evaluation using diameter data of digital cable core became a method of cable quality control . higher measuring precision and higher measuring speed of the diameter gauge was required
此外，由于数字通信电缆传输频带的提高，对均匀性要求也不断提高，采用直径信息来在线评估数字通信电缆的srl (结构回波损耗)成为也质量控制一种方法，这就对测径仪的测试性能提出了更高的要求。
