3.5. EUT Configuration on Test 

The following equipments are installed on conducted emission test to meet EN55013 and 
EN55022 requirement and operating in a manner which tends to maximize its emission 
characteristics in a normal application. 
3.5.1.BLU-RAY DISC SYSTEM 

Model Number   

   :   BDS575 

Serial Number 

   :   N/A 

3.5.2.Support Equipment      :  As Tested Supporting System Detail, in Section 2.2. 

3.6. Operating Condition of EUT 

3.6.1.Setup the EUT and simulators as shown in Section 3.2. 
3.6.2.Turn on the power of all equipments. 
3.6.3. Let the EUT worked in test mode (BD Play/USB Play/BD Live/FM Mode/Coaxial In/ 

AUX In / Component Video IN/ Optical In / HDMI In) and test it. 

3.7. Test Procedure 

The EUT was placed on a non-metallic table, 80cm above the ground plane. The EUT 
Power connected to the power mains through a line impedance stabilization network 
(L.I.S.N. #1).The other peripheral devices power cord connected to the power mains 
through a line impedance stabilization network (L.I.S.N.#3). This provided a 50ohm 
coupling impedance for the tested equipments. Both sides of AC line are checked to find 
out the maximum conducted emission levels according to the EN55013 and EN55022 
regulations during conducted emission test. 
 
The bandwidth of the test receiver (R&S Test Receiver ESHS10) is set at 10kHz. 
 
The frequency range from 150kHz to 30MHz is checked. The test result are reported on 
Section 3.8.   

3.8. Power Line Conducted Emission Test Results 

PASS. (All emissions not reported below are too low against the prescribed limits.) 
 

The EUT with the following test modes were tested and selected (mode 1~10) to read Q.P 
values, all the test results are listed in next pages.
