9.3 Test set-up
See annex B
The testing was performed in a fully anechoic chamber. The EUT and load, which are placed on a table
that is 0.8 meter above ground, The transmit antenna was located at a distance of 3 meters from the
EUT. The frequency range is swept from 80 MHz to 1000MHz with the signal 80% amplitude
modulated with a 1 kHz sine wave. The rate of sweep did not exceed 1.5×10-3 decade/s. The step size
was 1% of fundamental. The dwell time at each frequency shall be not less than the time necessary for
the EUT to be able to respond. The field strength level was 3V/m. The test was performed with the
EUT exposed to both vertically and horizontally polarized fields on each of the four sides.
