Test Procedures: As required by ETSI 300 328, field strength of radiated spurious

measurements were made in accordance with the procedures of the ETSI

EN 300 328 §5.3.10.

For conducted measurement the device was directly connected to the

EUT with a High Pass Filter. For Radiated measurement the EUT was

placed on a wooden table inside a 3 meter semi-anechoic chamber.

The measurement antenna was placed at a distance of 3 meters from the

EUT. During the tests, the antenna height and polarization as well as EUT

azimuth were varied in order to identify the maximum level of emissions

from the EUT. The test was performed by placing the EUT on 3

orthogonal axis. Test was performed at lowest and highest channel.

The EUT is removed and replaced with a substitution antenna. A signal

generator was connected to the substitution antenna by a non-radiating

cable. The absolute levels of the spurious emissions were measured by

the substitution.
