Introduction In the design and manufacturing of modern electronic devices, electromagnetic interference (EMI) and electromagnetic compatibility (EMC) testing are crucial to ensuring product performance and safety. The Three Loop Antenna is a specialized antenna used for EMI/EMC testing. Due to its unique design and excellent performance, it is widely used for radiation testing of various electroni...
Introduction In the field of electromagnetic interference (EMI) and electromagnetic compatibility (EMC) testing, antennas play a crucial role in measuring and analyzing electromagnetic fields. The triple-loop antenna is a specialized type of antenna designed for specific applications in these areas. The LISUN VVLA-30M Three Loop Antenna is a notable example of this technology, providing an efficie...
There are many customers feedback that their LED luminaires can’t pass CE Certificate EMI Radiation Test (30-300MHz) in 2019 year but it is the same one can be passed last year. Why this happen? The main reason is the new EMI test standard were updated to CISPR15:2018. The EMI Test is the most important and difficult to test for the LED luminaires. This article LISUN engineer will take us to...
With the widespread use of electrical and electronic equipment, the problem of electromagnetic disturbance has also brought electromagnetic pollution. EMC(Electro Magnetic Compatibility) refers to the ability of a device or system to operate within its electromagnetic environment without incurring unacceptable electromagnetic interference to any device in its environment. EMC testing, one the one ...
The three loop antenna are often used during electromagnetic radiation test. Lisun three loop antenna VVLA-30M is a standard measurement antenna according to CISPR15-2005. It can be used with Lisun EMI-9KB or EMI-9KA EMI Receiver System for EUT magnetic field radiation test measurement between X, Y and Z planes. VVLS-30M is a big antenna with 2m diameter, which is used for testing frequency bel...
Standards GB17743-2007 / CISPR 15:2005 <Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment> instead of the standards GB 17743-1999 and GB 15734-1995. The limits for the 2m diameter loop antenna apply to equipment not exceeding a length of 1.6m, those for the 3m loop diameter for the equipment having a length in between 1.6m and...
