Research on Calibration Method of Cable Analyzer in Far-end Attenuation-to-Crosstalk Ratio Parameter
摘要
Abstract
Far-end attenuation-to-crosstalk ratio (ACR-F) is the primary parameter of digital balanced cable,also the essential test item in cable analyzer.Have proposed a calibration method on ACR-F of cable analyzer,which utilize network analyzer (NA) and impedance converter to measure insertion loss (IL) and far-end crosstalk (FEXT) in reference cable separately,and acquire the derived results.And the calibration method of ACR-F is direct comparison between the NA and cable analyzer on the reference cable.The method is confirmed through comparison with Psiber(R) Wirexpert series cable analyzer,and extended uncertainty is also listed.关键词
