scope:

This part of IEC 60512 specifies the test methods fortransmission performance for M12-style connectors up to 500 MHz. Itis also suitable for testing lower frequency connectors if theymeet the requirements of the detail specifications and of thisstandard. NOTE 1 All figures show equipment for connectorsaccording to IEC 61076-2-109 as an example. The test methodsprovided herein are: ? insertion loss, test 29a; ? return loss,test 29b; ? near-end crosstalk (NEXT) test 29c; ? far-end crosstalk(FEXT), test 29d; ? transverse conversion loss (TCL), test 29f; ?transverse conversion transfer loss (TCTL), test 29g. For thetransfer impedance (ZT) test, see IEC 60512-26-100, test 26e. Forthe coupling attenuation see ISO/IEC 11801. All test methods applyfor two and four pair connectors. NOTE 2 All figures show schemesfor four pair cabling and are also suitable for two paircabling.
