4.1.3 TEST PROCEDURE 

a. The EUT was placed 0.8 meters from the horizontal ground plane with EUT being connected 

to the power mains through a line impedance stabilization network (LISN). All other support 

equipments powered from additional LISN(s). The LISN provide 50 Ohm/ 50uH of coupling 

impedance for the measuring instrument.   

b. Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back 

and forth in the center forming a bundle 30 to 40 cm long. 

c. I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the 

cable may be terminated, if required, using the correct terminating impedance. The overall   

length shall not exceed 1 m. 

d. LISN at least 80 cm from nearest part of EUT chassis. 

e. For the actual test configuration, please refer to the related Item –Block Diagram of system 

tested (please refer to 3.3).

4.1.7 EUT OPERATING CONDITIONS 
The EUT exercise program used during radiated and/or conducted emission measurement was 
designed to exercise the various system components in a manner similar to a typical use. The 
standard test signals and output signal as following: 
1. Input signal: A sinusoidal signal at 1kHz. 
2. Output signal: The audio output signal shall be adjusted by the volume control to be 1/8 of the 
rated output power for each output 
This operating condition was tested and used to collect the included data.
