IEC 62228的本部分规定了网络条件下CXPI收发器集成电路电磁兼容性评估的测试和测量方法。它定义了测试配置、测试条件、测试信号、故障标准、测试程序、测试设置和测试板。本规范适用于标准CXPI收发器IC和带有嵌入式CXPI收发器的IC，涵盖-射频干扰发射，-射频干扰抗扰度，-脉冲抗扰度和-静电放电抗扰度（ESD）。

This part of IEC 62228 specifies test and measurement methods for the EMC evaluation of CXPI transceiver ICs under network condition. It defines test configurations, test conditions, test signals, failure criteria, test procedures, test setups and test boards. This specification is applicable for standard CXPI transceiver ICs and ICs with embedded CXPI transceiver and covers- the emission of RF disturbances,- the immunity against RF disturbances,- the immunity against impulses and- the immunity against electrostatic discharges (ESD).
