IMMUNITY TO RADIATED ELECTROMAGNETIC FIELD, KEYED CARRIER
8.1 Operating environment
The test was performed in a semi-anechoic shielded chamber.
Temperature:
24
C
Relative Humidity:
51 %
8.2 Test set-up
The EUT was placed on a non-metallic table 0,8 m above the reference ground plane and was
operated according to its specified operating mode.
operated according to its specified operating mode.
Ferrite tiles/absorbers were placed on the RGP between the EUT and the antenna to reduce the
reflections from the RGP. The cables were exposed for the electromagnetic field for 1 m vertically
and 1 m horizontally.

8.3 Generation of the electromagnetic field
The electromagnetic field is generated from a computer controlled signal generator. The output
power is amplified and then radiated from broad band log periodic antennas. For each sweep a
pre-recorded empty chamber calibration file is used to establish the required field strength. When
using these files the field strength inside an area of 1,5 m x 1,5 m is in accordance with the
standard.

8.5 Measurement uncertainty
The measurement uncertainty is: ± 0,82 V/m.
Measurement uncertainty is calculated in accordance with EA-4 /02:1997. The measurement
uncertainty is given with a confidence of 95%. The uncertainty calculations exclude influence of
phenomena like inhomogenity of the electric field intensity.
