IEC 61967-4:2021
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 Ω resistive probe and RF voltage measurement using a 150 Ω 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 Ω method has been reduced to 30 MHz; - Annex G with recommendations and guidelines for frequency range extension beyond 1 GHz has been added.
