IEC 60512-29-100:2015规定了高达500 MHz的M12型连接器传输性能的测试方法。如果低频连接器满足详细规范和本标准的要求，它也适用于测试它们。本文提供的测试方法是: -插入损耗，测试29a； -回波损耗，测试29b； -近端串扰(下一个)测试29c； -远端串扰(FEXT)，测试29d； -横向转换损耗(TCL)，测试29f； -横向转换传递损失(TCTL)，测试29g。传递阻抗（ZT）测试参见IEC 60512-26-100，测试26e。耦合衰减参见ISO/IEC 11801。所有测试方法适用于两对和四对连接器。 关键词:连接器，信号完整性，M12型连接器

IEC 60512-29-100:2015 specifies the test methods for transmission performance for M12-style connectors up to 500 MHz. It is also suitable for testing lower frequency connectors if they meet the requirements of the detail specifications and of this standard. The test methods provided 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 the transfer impedance (ZT) test, see IEC 60512-26-100, test 26e. For the coupling attenuation see ISO/IEC 11801. All test methods apply for two and four pair connectors. Key words: Connectors, Signal Integrity, M12 Style Connector
