IEC 61967-4 Ed. 2.0 b – Integrated Circuits – Measurement Of Electromagnetic Emissions – Part 4: Measurement Of Conducted Emissions – 1 Ohm/150 Ohm Direct Coupling Method

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.
