5. Input immunity to RF voltages (in differential mode)(S1)
5.1 Test criteria and test procedure
Operating environment;
Temperature         
: 17 ℃
Relative Humidity  
: 42 %
The criterion concerning acceptable  sound interference is a wanted to 
unwanted audio signal ratio of ≥40dB at a wanted signal level of 50mW.
The EUT was placed by 0.1m above a metallic ground plane of dimensions 
2 x 1 m. The measuring set-up was shown in figure 3 EN55020(2007).
The principle of operation was similar to the measuring set-up of figure 3 in
EN55020(2007).
The low pass filter was added to prevent the influence of the measuring results
by harmonics of the unwanted signal generators.
The speaker outputs of the EUT were applied to an 8Ω purely resistive load
(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 
5.2 Measurement uncertainty
Antenna input immunity ± 2.0dB
5.3 Test result of input immunity to RF voltages.
The equipment does comply with the requirements.
For the measurement data, see annex A

6. Immunity to RF voltages(S2a)
6.1 Test criteria and test procedure
Operating environment;
Temperature         
: 17 ℃
Relative Humidity  
: 42 %
The EUT was placed 0.1m above a metallic ground plane of dimensions 2 x1m.
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 ≥40dB at a wanted signal level of 50mW.
The audio output power was measured with a 0.5 - 3kHz 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 measurement are performed with TS9980 
6.2 Measurement uncertainty
Immunity to conducted voltage : ± 2dB.
6.3 Test result immunity to conducted voltage.
The equipment does comply with the requirements.
For the measurement data, see annex B.

7. Immunity to RF voltages (in common mode)(S2b)
7.1 Test criteria  and test procedure
Operating environment;
Temperature         
: 17 ℃
Relative Humidity  
: 42 %
During the test of immunity to RF voltages(in common mode), the EUT was 
placed 0.1m above a metallic ground plane of dimensions 2 x 1m.
The criterion concerning acceptable sound interference is a wanted to 
unwanted audio signal ratio of ≥40dB at a wanted signal level of 50mW
The requirements for receivers,multifuction equipment and video tape 
equipment concerning the immunity to RF voltages in common mode are 
restricted to the antenna terminals and to the frequency range from 26㎒ to
30㎒. The cables linking the coupling units to the EUT was short .
A bandpass filter was connected to the test system and was used for the EUT 
AF outputs.
All unused inputs/outputs of the coupling units was terminated with the 
proper resistance.
The power cable of the EUT was uniformly bundled together and as short
as possible.
The measurement are performed with TS9980 
7.2 Measurement uncertainty
Immunity to conducted currents : ± 2dB
7.3 Test result immunity to conducted currents.
The equipment does comply with the requirements.
For the measurement data,  see annex C.
