Test method for coaxial cable structural return loss 同軸電纜結(jié)構(gòu)回波損耗試驗(yàn)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,由于數(shù)字通信電纜傳輸頻帶的提高,對均勻性要求也不斷提高,采用直徑信息來在線評估數(shù)字通信電纜的srl (結(jié)構(gòu)回波損耗)成為也質(zhì)量控制一種方法,這就對測徑儀的測試性能提出了更高的要求。
