The new integrated circuit chip GB/T 44807.1-2024 integrated circuit EMC modeling standard has been formally released on October 26, 2024 and implemented, the standard proposes CE/CI/RE/RI/CPI five different tests of EMC modeling framework and four types of modeling...
This article mainly introduces the GB/T 17743-2021 new version of the EMC standard for lamps and lanterns compared to the GB/T 17743-2017 version of the updated content, and lists the scope of applicable lamps and lanterns and the list of inapplicable lamps and lanterns products of the new version of the 2021 standard.
Many EMC engineers will use a one-size-fits-all approach to rectify EMC problems to contain the outward interference of the product, while also preventing other equipment from interfering with their own equipment. How to curb it across the board? This is what this article says to talk about the two effective ways to attenuate EMI radiation interference: metal chassis cabinet screen...
Extremely low frequency ELF electric and magnetic fields (EMFs) occupy the lower part of the electromagnetic spectrum in the frequency range 0-3000 Hz.ELF EMFs are generated by charged particles. Artificial sources are the main source of very low frequency EMFs, usually associated with Australian 50 Hz or some other...
RF radio testing is the process of measuring the energy of electromagnetic fields propagating in the living environment, we can use receiving antennas and receivers in the laboratory with the use and capture the power of these radio signals, this test is called EMC testing; we can also use radio RF testing in real life applications to raise...
RS radiated immunity and CS conducted immunity in EMC electromagnetic compatibility test need to configure power amplifier, but how much do you know about power amplifier? Most of the customers can only rely on the products provided by the suppliers to choose the EMS test system, how to choose the RF power amplifier for EMC test...
This article mainly shows the EU CE certification of lamps and lanterns products EMC test requirements and common problems, including the EU certification standards for lamps and lanterns products, test items, limit value requirements and other content, and detailed introduction of lamps and lanterns and other similar products harmonic current test requirements and some did not pass the certification of the rectification case.
This article introduces the CDN and CDNE are defined and used by the EMC electromagnetic compatibility testing industry test standard CISPR15, this article through the introduction of CDN and CDNE's name, purpose, voltage division coefficient common-mode impedance, etc. This article explains in detail the difference between the CDN and CDNE, and facilitates...
