IEC 61967-4:2021 is available as IEC 61967-4:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61967-4:2021 specifies a method to measure the conducted electromagnetic emission (EME) of integrated circuits by direct radio frequency (RF) current measurement with a 1 resistive probe and RF voltage measurement using a 150 coupling network. These methods ensure a high degree of reproducibility and correlation of EME measurement results. This edition includes the following significant technical changes with respect to the previous edition:
- frequency range of 150 kHz to 1 GHz has been deleted from the title;
- recommended frequency range for 1 method has been reduced to 30 MHz;
- Annex G with recommendations and guidelines for frequency range extension beyond 1 GHz has been added.
