Relationship between EMC, EMI and EMS

1、RE： Radiation emission (RE)（100k～2.7G)Radiated Emission ： Radiation disturbance test

2、CE： Conducted interference CE（conduction emission）（150kHz～108MHz）： Conducted disturbance test

3、RS： Radiated immunity ： Radio frequency electromagnetic field radiation immunity test

4、CS： Conducted immunity ： RF field induced conducted disturbance immunity test

5、EFT： Transient pulse interference ： Electrical fast transient burst immunity test

6、DIP： Voltage drop ： Voltage dips , Short time interruption and voltage variation immunity test

7、ESD： Static electricity ： Electrostatic immunity test

8、Surge： Surge ： Immunity surge （ impact ） Immunity test

About RE and RSE The difference between ：

Radiation spurious ( abbreviation RSE) It refers to when the mobile station is connected with a non radiative pure resistance load or in the receiver state , Generated or amplified by the mobile station through the mobile station housing 、 Power Supply 、 Control equipment 、 Emission beyond the working frequency radiated by each audio cable .

In current international standards “ Radiation spurious ” They are basically divided into RF projects (RF) Inside , Domestic standards ( With YD1032 It is typical ) It is divided into electromagnetic compatibility (EMC) Within the test content of .

from RSE The definition of ,RSE It's not just the noise from the transmitter , It covers the entire spurious domain , Both intentional launch , Also contains EUT Unintentional emission of other circuits not related to the transmitter in .3GPP After the promulgation of the standard ,RSE Testing becomes a measure of wireless products EMI Important test of performance . meanwhile , It's not hard to find out ,RE and RSE The scope of the test overlaps .
