5. Immunity to RF voltages(S2a)

5.1 Test criteria and test procedure

Operating environment;
Temperature         

: 18 ℃

Relative Humidity  

: 55 %

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 Ver.2.9.

5.2 Measurement uncertainty

Immunity to conducted voltage : ± 2dB.

5.3 Test result immunity to conducted voltage.

The equipment does comply with the requirements.

For the measurement data, see annex A.

6. Immunity to ambient electromagnetic fields (S3)

6.1 Test criteria  and test procedure

Operating environment;
Temperature         

: 18 ℃

Relative Humidity  

: 55 %

The EUT was placed on a non-metallic support by 0.1m above the lower 
conductor in the center of the stripline.
The wanted signal was fed to all input terminals respectively .The unwanted 
signal is fed to a matching network of the stripline.
The ground connection of the mains filter(M) was directly connected to the
jacky.
All unused input/output connections on the EUT were terminated and 
shielded with the proper resistance.
The power supply to the mains of the EUT was attached to the mains filter(M).
Ferrite rings for this test was required on all test cables inside the shielded 
room.

The measurement are performed with TS9980 Version 2.9.

6.2 Measurement uncertainty

Radiated fields  : ± 2dB

6.3 Test result immunity from radiated fields.

The equipment does comply with the requirements.

For the measurement data, see annex B.
