This is Part 2-1 of GB/T 6113.
This Part was drafted in accordance with the rules in GB/T 1.1-2009.
This Part serves as a replacement of GB/T 6113.201-2017 Specification for Radio Disturbance
and Immunity Measuring Apparatus and Methods - Part 2-1: Methods of Measurement of
Disturbances and Immunity - Conducted Disturbance Measurements. In comparison with GB/T
6113.201-2017, the main technical changes are as follows:
---In accordance with the principle of equivalence, “NOTE” is added to the Scope to reflect
the status of the EMC basic standard, and the relations between the product (category)
standards of the relevant horizontal technical committees and the basic standard, and to
consider necessary cooperation in the formulation of EMC standards;
---Four terms and definitions are added (see Chapter 3);
---Abbreviations are added (see 3.2);
---EUT arrangement is added (see 6.4.1);
---The working status of multi-function equipment is added (see 6.4.7);
---The determination of EUT arrangement that maximizes emissions is added (see 6.4.8);
---The recording of measurement results is added (see 6.4.9);
---The test set-up and measurement procedure using the CDNE in the frequency range 30
MHz ~ 300 MHz are added (see Chapter 9);
---The basic requirements for measurements on telecommunications ports are added (see
Appendix G);
---The specific guidance for conducted disturbance measurements on telecommunication
ports is added (see Appendix H);
