What is an EMC Test Chamber? EMC Test, also known as Electro Magnetic Compatibility (EMC), stands for Electro Magnetic Compatibility, referring to the comprehensive evaluation of the size of electromagnetic field interference (EMI) and anti-interference ability (EMS) of electronic products, which is one of the important indicators of product quality. The measurement of electromagnetic compatibilit...
In the field of product development, electromagnetic compatibility (EMC) research has become increasingly important. Many engineering departments hope to have their own EMC testing environment. In the EMC test, the radiation launch measurement of the product is particularly important for the test environment and equipment. The environment for radiation launch requirements is an open field (OATS) o...
A conductive barrier entirely envelops a gadget in order to shelter it from outside interference. This is known as electromagnetic shielding. The gadget can also prevent emissions from interfering with other devices in the same area. It is an insulating method. This is because it lessens or stops the transfer of energy. In this scenario, electromagnetic energy acts as a barrier between a high outp...
Working principle of shielding room: Computers, communicators, and electronic equipment will generate electromagnetic waves of certain strength during normal operation. The electromagnetic waves may interfere with other equipment or be received by special equipment to steal their work. At the same time, these electronic devices also need to ensure their normal operation in an electromagnetic envir...
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...
