4.2 Block diagram and test set up
According to EN 55013
The measurement was applied in an semi-anechoic chamber.
The EUT and simulators were placed on a 0.8m high wooden turntable above the
horizontal metal ground plane. The turn table rotated 360 degrees to determine the
position of the maximum emission 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 antenna was used as receiving antenna. Both horizontal and vertical
polarization of the antenna were set on measurement. In order to find the maximum
emission, all of the interface cables were manipulated according to
EN55013/EN55022 requirement during radiated test.
The bandwidth setting on R&S Test Receiver ESI26 was 120kHz.
The frequency range from 30MHz to 1000MHz was checked.

4.4 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:
Measurement uncertainty of mains terminal disturbance voltage:
± 5.2dB
The measurement uncertainty is given with a confidence of 95%, k=2.
4.5 Additions, Deviations and Exclusions from Standards
