IN THE FREQUENCY RANGE 30 MHZ TO 1000 MHZ
7.1 Operating environment
Temperature: 21
°C
Relative Humidity:
48 %
Measurements were performed in a semi-anechoic chamber.
7.2 Test set-up and test procedure
The EUT was positioned in order to emit maximum disturbance.
Photos of test setup.
An overview sweep with peak detection of the electric field intensity was performed in a semi-anechoic
chamber. The overview sweep was performed with the measurement receiver in max-hold and the antenna
was varied between 1 to 4 m in both horizontal and vertical polarisation. The measurements were repeated
with the EUT rotated in 45-degree steps.
The radiated disturbance electric field intensity was measured at a distance of 3 m and the EUT was placed
on a non-metallic table, 0,8 m above the reference ground plane.

7.3 Measurement uncertainty
Radiated disturbance electric field intensity, 80-300 MHz:
±4,6 dB
Radiated disturbance electric field intensity, 200-1000 MHz:
±4,8 dB
The measurement uncertainty describes the overall uncertainty of the given measured value during
operation of the EUT in the above-mentioned way.
Measurement uncertainty is calculated in accordance with EA-4 /02:1997.
The measurement uncertainty is given with a confidence of 95%.
