      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.

6.5. Test protocols 

 

Date: January 21, 2008 

 

The equipment does comply with the requirements. 

 

Operating condition: The EUT continuously operated with audio frequency 
of 1,000 ㎐  and color bar from DVD Test DISC. 
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.
