Test Procedure
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
EN55022:1998 on radiated measurement.
Radiated emissions were invested over the frequency range from 30MHz to1GHz using a
receiver bandwidth of 120kHz. Radiated was performed at an antenna to EUT distance of 10
meters.

Test Result
The emission from the EUT was below the specified limits. The worst-case emissions are shown in
section 13. The acceptance criterion was met and the EUT passed the test.
