Study On Dual Band Test Method For Radiated,Radio-frequency,Electromagnetic Field Immunity

Nowadays,the rapid development of science and technology brings more convenience to our life and more and more serious electromagnetic pollution to our life surroundings.The electromagnetic compatibility ability of electronic products is a key factor to ensure that electronic products are able to coexist with each other.The radio frequency electromagnetic field radiation immunity test is a very important item and topic in EMC field.Testing on products' electromagnetic RF radiation susceptibility ability is a very critical and essential aspect of the EMC test and it's also a very basic test item in the most international standardization certification system,the method of which is exactly the subject of study in this essay.The current RF electromagnetic field susceptibility test method employs a routine method of applying interference signal with certain level on products by means of antenna radiation exposure on one frequency point followed by another generated from RF power amplifier within its working frequency range.Such method has been acknowledged by international certification facilities including IEC(International Electrotechnical Commission)and is thus widely applicable all around the world.This paper establish a more efficient new radio frequency electromagnetic field radiation immunity test method —— Dual band radio frequency electromagnetic field radiation immunity test method,which relies on the condition of existing technology and equipment.This paper verify whether the new test method is reliable or accurate by comparing the results of the two kinds of test methods to provide a basic reference for the relevant products of professional technical committee or users and manufacturers.
