3. TEST SPECIFICATIONS 
 

      EN55020(2007) : Electromagnetic immunity of broadcast receivers and associated equipment. 
 

      No additions, deviations or exclusions have been made from standard. 
 

      Purpose of test: To determine whether the equipment under test fulfils the EMC immunity   
      requirements of the standard stated in section 3.1 
 

   3.4.1 Location 
     386-1, Ho-dong, Cheoin-gu, Yongin-si, Gyeonggi-do, 449-100, Korea

Test 

Passed the test 

 Electrostatic Discharge (EN 61000-4-2) 

 

  Radio-frequency, Electromagnetic Field Keyed Carrier Immunity test 

 

 

 Electrical Fast Transients/Burst (EN 61000-4-4) 

 

 

The equipment does comply with the requirements 

 

 

5. Input immunity to RF voltages (in Differential mode) (S1) 
 

 
      Operating environment; 
 Temperature 

20  ℃ 

 

Relative Humidity 

40 % 

 
      The criterion concerning acceptable sound interference is a wanted to unwanted   
   audio signal ratio of ≥40 dB at a wanted signal level of 50 mW. 
 
      The EUT was placed 0.1m above a metallic ground plane of dimensions 2 x 1 m. 
      The measuring set-up was shown in Figure 1 EN55020 (2007). 
      The principle of operation was similar to the measuring set-up of Figure 1 EN55020 (2007). 
       
      The low pass filter was added to prevent influence of the measuring results by 
        harmonics of the unwanted signal generators. 
 
      The lineout of the EUT were applied to an 22k ohm purely resistive road (Ro) 
        and then to the AF inputs of the test system. 
      The power supply of the EUT was connected to a standard voltage source 
   (without special filters). 
   The measurements were performed with test software TS9980 Ver.2.1 
 

 
    Antenna input immunity +/- 3.0dB 
 

 
        The equipment does comply with the requirements. 
 
    For the measurement data, see Annex A 
 

 

6. Immunity to RF voltages (S2a) 
 

 
      Operating environment; 
 Temperature 

22  ℃ 

 

Relative Humidity 

40 % 

 
      The EUT was placed 0.1m above a metallic ground plane of dimensions 2 x 1 m. 
      The wanted signal was fed to all input terminals respectively and the unwanted   
        signal was fed to mains input, audio output and input terminals respectively. 
 
      The criterion concerning acceptable sound interference is a wanted to unwanted   
    audio signal ratio of ≥40 dB at a wanted signal level of 50 mW. 
 
      The audio output power was measured with a 0.5 - 3 kHz band-pass filter. 
      The audio analyzer was applied without a weighting filter. 
      The ground connection of the input matching network (Rci), output matching network (Rco), 
    and mains filter (MSF) were directly connected to the metal table. 
   The mains filter (MSF) was connected to ground while the other matching networks 
    are only connected to ground when they are being used as injection ports. 

 

   The measurements were performed with test software TS9980 Ver.2.1 
 

 
        Immunity to conducted currents : +/- 3 dB 
 

 
        The equipment does comply with the requirements.
