What is BS EN IEC 61967‑4 about?
BS EN IEC 61967‑4 is the fourth part of a series of documents on integrated circuits. BS EN IEC 61967‑4 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.
Who is BS EN IEC 61967‑4 for?
BS EN IEC 61967‑4 on measurement of electromagnetic emissions and integrated circuits are useful for:
- Electrician and technicians who can measure the emissions
- The professionals who know the installation of electrical wiring
- Electrical engineers who are working in the aviation and space center
Why should you use BS EN IEC 61967‑4?
Measurement of electromagnetic emission is important in Astronomy because it helps us see the universe. BS EN IEC 61967‑4 helps to use methodology aids the test technician to overcome challenges such as the changes of background noise, evaluating accurately all the functional modes.
The main advantage of using BS EN IEC 61967‑4 is that we can perform instantaneous measurements, avoiding changes in the background noise that introduce confusion to the EMC (Electromagnetic capability) assessment.
What’s changed since the last update?
BS EN IEC 61967‑4:2021 supersedes BS EN 61967‑4:2002+A1:2006. BS EN IEC 61967‑4:2021 includes some technical changes concerning BS EN 61967‑4:2002+A1:2006. These include:
