4.5.  EUT Configuration on Test 

The configurations of EUT are listed in Section 3.5 

4.6.  Operating Condition of EUT 

4.6.1. Setup the EUT and simulators as shown in Section 4.2. 
4.6.2. Turn on the power of all equipments. 
4.6.3. The EUT link to PC and which transmitted data via running “TFGEN.exe”           

software., In order to make reliable emission measurement representative of high 
LAN utilization it is only necessary to create a condition of LAN utilization in excess 
of 10% and sustain that level for a minimum of 250ms.   

4.6.4. The other peripheral devices were driven and operated in turn during all testing.

4.7.  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). This provided a 50-ohm coupling impedance for the EUT (Please refer to 
the block diagram of the test setup and photographs). The other peripheral devices power 
cord connected to the power mains through a line impedance stabilization network 
(L.I.S.N.#3). Both sides of power line were checked for maximum conducted interference. 
In order to find the maximum emission, the relative positions of equipments and all of the 
interface cables were changed according to EN 55022: 2010+AC:2011 on Conducted 
Disturbance test. 
And connected to the telecommunication ports through ISN. Both sides of 
telecommunication line are investigated to find out the maximum conducted emission 
according to EN 55022: 2010+AC:2011 regulations during conducted disturbance test. 
 
The bandwidth of the test receiver (R&S Test Receiver ESHS 10) is set at 10kHz. 
 
The frequency range from 150kHz to 30MHz is checked. The test result are reported on 
Section 4.8. 

4.8.  Conducted Disturbance at Telecommunication Ports Test Results
