The EUT and simulators are connected to the main power through a line impedance stabilization 

network (L.I.S.N.). This provides a 50 ohm /50uH coupling impedance for the measuring equipment. 
The peripheral devices are also connected to the main power through a LISN that provides a 50ohm 
/50uH coupling impedance with 50ohm termination. (Please refers to the block diagram of the test 
setup and photographs.) 

Both sides of AC line are checked for maximum conducted interference. In order to find the maximum 
emission, the relative positions of equipment and all of the interface cables must be changed according 
to ETSI EN 301 489-1:V1.6.1 (2005-09) on conducted measurement. 
The bandwidth of the field strength meter (R & S Test Receiver ESCS 30) is set at 9kHz. 

The mains voltage shall be supplied to the EUT via the LISN when the measurement of 

telecommunication port is performed. The common mode disturbances at the telecommunication port 
shall be connected to the ISN, which is 150ohm impedance. Both alternative cables are tested related to 
the LCL requested. The measurement range is from 150kHz to 30MHz. The bandwidth of measurement 
is set to 9kHz. The 60dB LCL ISN is used for cat. 5 cable, 50dB LCL ISN is used for cat. 3 and 80dB 
LCL is wed for alternative one. 

According to ETSI EN 301 489-1:V1.6.1 (2005-09) 
           EN 55022:1998+A1: 2000+A2: 2003

The emission from the EUT was below the specified limits. The worst-case emissions are shown in 
section 12. The acceptance criterion was met and the EUT passed the test.

The EUT and its simulators are placed on a turn table which is 0.8 meter above ground. The turn table 
can rotate 360 degrees to determine the position of the maximum emission level. The EUT was 
positioned such that the distance from antenna to the EUT was 10 meters.The antenna can move up 
and down between 1 meter and 4 meters to find out the maximum emission level.   
Both horizontal and vertical polarization of the antenna are set on measurement. In order to find the 
maximum emission, all of the interface cables must be manipulated according to 

ETSI EN 301 

489-1:V1.6.1 (2005-09)

 on radiated measurement. 

The additional motch filter below 1GHz was used to measure the level of harmonics radiated emission 
during field dtrength of harmonics measurement. The bandwidth below 1GHz setting on the field 
strength meter (R&S Test Receiver ESCS 30 )is 120 kHz, and 1MHz bandwidth is adpted above 1GHz. 
The frequency range from 30MHz to 10

th

 harmonics is checked. 

According to ETSI EN 301 489-1:V1.6.1 (2005-09)
