EMC test

The radio spectrum consists of all frequencies that have electromagnetic radiation, which spreads energy in the form of waves and propagates through space. Longer wavelengths and lower frequencies make up the radio spectrum. Shorter wavelengths and higher frequencies make up the spectrum. We...

EMC testing process requires frequent conversion of dBm, dBμV, dBμA and other units of dB conversion formula, linear to logarithmic display conversion by heart is difficult to complete. This article describes how to quickly use the computer for dB conversion method...

Integrated circuits (ICs) are often the ultimate source of unintentional electromagnetic radiation from electronic devices and systems. However, ICs are too small to radiate on their own. In order to radiate fields strong enough to cause interference problems, ICs ICs are coupled in a way that EMC interference...

This article describes the CFR Part 15 - FCC PART 15 certification test standard introduced by the U.S. Federal Communications Commission FCC, the standard gives the basic classification of the device under test that needs to obtain authorization and does not need to obtain authorization,...

This paper introduces the source and test items of GB/T 37414.1-2019 EMC test standard for industrial robots, and details the standard references for static electricity, surge, pulse group, radio frequency electromagnetic field immunity, conducted immunity,...

This paper describes the difference between two different coupling networks, CDN and CDNE, and details the technical parameter requirements of the EN55015 and CISPR15-2018 standards for CDNE as well as the CDNE test methods bu...

EMC rectification process we need to use a variety of different filter circuits and components, filter capacitors are the most commonly used filter pieces, this article with a simple graphic details of the ordinary capacitors, three-terminal capacitors, through the heart of the capacitors and other three different kinds of filter capacitors ...

This paper describes in detail the source of the CCC compulsory product certification system, role, release time, etc., explains the establishment of China's 3C certification is because with China's accession to the WTO, according to the WTO agreement and the international rules of the road, China has established a 3C certification system...
