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 Wirexpert series cable analyzer, and extended uncertainty is also listed.
