3.1.2 TEST PROCEDURE 

a. The EUT was placed 0.4 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 –EUT Test Photos.
