IEC 61967 2 Integrated Circuit Radiated Emission Testing
The IEC 61967-2 standard specifies the methods for determining the radiated emission of integrated circuits (ICs). This test is critical in ensuring that electronic devices do not interfere with other equipment or cause harmful emissions. In automotive applications, where reliability and safety are paramount, this testing ensures compliance with international standards to protect against electromagnetic interference.
Compliance with IEC 61967-2 is essential for manufacturers of automotive components such as vehicle control units, engine management systems, infotainment systems, and other electronic modules. The test involves exposing the IC under test to a controlled environment where it emits radiated signals in the frequency range from 80 MHz to 3 GHz.
The testing process requires precise setup and measurement equipment such as an anechoic chamber, a spectrum analyzer, and calibrated antennas. These instruments ensure accurate data collection for analysis. The test aims at quantifying the emission levels that may affect other electronic systems within the vehicle or external devices in close proximity.
During the testing process, it is crucial to prepare the IC specimens by ensuring they are free from any foreign particles and have a clean surface. This step prevents inaccurate measurement results due to extraneous signals. The specimen is then placed into an anechoic chamber where radiated emissions can be measured.
The test parameters include setting up the frequency range, power output levels, and exposure duration according to IEC 61967-2. Compliance officers should ensure that all equipment used meets the specified standards for accuracy and reliability. For quality managers, this testing is a key step in ensuring product compliance with international regulations.
R&D engineers play a critical role in optimizing IC designs by understanding these test parameters and adjusting their designs accordingly to meet emission limits. This service ensures that automotive components are safe and reliable, contributing to the overall safety of vehicles on the road.
