The EUT and simulators were placed on a 0.8m high wooden t
ground plane. The turn table rotated 360 degrees to determine the position of the maximum emissio
level. The EUT was set 3 meters away from the receiving antenna, which was mounted on an antenna
mask. The antenna moved up and down between from 1meter to 4 meters to find out the maximum
emission level.
Broadband anten
antenna were set on measurement. In order to find the maximum emission, all of the interface cable
were manipulated according to EN55022 requirement during radiated test.
The bandwidth setting on R&S Test Receiver ESBI 40 was 120kHz.
The frequency range from 30MHz to 1000MHz was checked.

5.5 Measurement uncertainty
The measurement uncertainty describes the overall uncertainty of the given measured value
during the operation of the EUT.
Measurement uncertainty is calculated in accordance with CISPR 16-4-2: 2003.
Measurement uncertainty of mains terminal disturbance voltage :
during the operation of the EUT.
Measurement uncertainty is calculated in accordance with CISPR 16-4-2: 2003.
Measurement uncertainty of mains terminal disturbance voltage :
± 5.2dB
The measurement uncertainty is given with a confidence of 95%, k=2.
