RANGE 0.15MHz TO 30MHz

 

 

   5.1. Operating environment 

Temperature 

: 18℃ 

Relative humidity  : 45 % 

 

5.2. Test set-up and procedure 

 

 

 

The mains terminal disturbance voltage was measured with the EUT in a 
Screened room. The EUT was placed on a non-metallic table by 0.8m above   
the metallic grounded floor and 0.4m from the reference ground panel (RGP) 
wall. The distance to other metallic surfaces was at least 0.8m. 
The EUT was tested with the outer conductor of the antenna input connected 
as well as not connected to the ground terminal of the AMN. 
The level of the test signal was 500mV (1 KHz) at coaxial RF input connector. 
Amplitude measurements were performed with a quasi-peak detector and, 
If required, with an average detector. 

 
5.3. Measurement uncertainty 

 

Mains terminal disturbance voltage, quasi-peak detection:  ±2.0dB 

 

Mains terminal disturbance voltage, average detection      :  ±2.0dB 

 

The measurement uncertainty describes the overall uncertainty of the given 

 

measured value during the operation of the EUT in the above-mentioned way.

      6.2. Test set-up and procedure 
 

The EUT was placed on a non-metallic table of 0.8m height. At the side of the 

 

EUT a non-metallic table of 6m length was placed to provide for movement of 

 

the absorbing clamp. The absorbing clamp was applied successively to all leads 

 

whose length was 25 ㎝  or longer, unscreened or screened. For the read, the 

 

maximum measured value at each frequency which was obtained when the 

 

absorbing clamp is moved along the lead was registered. No metallic object, 

 

including a possible other unit of the EUT or any person, was closer to the lead 

 

or unit than 0.8m. All screened and unscreened cables were measured with an 
absorbing clamp, according to EN55013, 5.6. 

 
   6.3. Measurement uncertainty 
 

Radio interference power:  ±2.0 ㏈ 

 

The Measurement uncertainty describes the overall uncertainty of the given   
measured value during operation of the EUT in the above-mentioned way.

The equipment does comply with the requirements. Operating condition: The   

 

EUT continuously operated with audio frequency of 1,000 ㎐ color bar being 

 

supplied from the iPod. An absorbing clamp was placed around all leads.   

At each mode, the maximum value at each testing frequency and each output   
lead was registered and attached as follows.
