EN 301 908-9 Electromagnetic Compatibility and Radio Spectrum - IMT-2000 Base Stations Test for Third Generation Cellular Networks

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN 301 908-9 test. This standard relates to IMT-2000 Third Generation cellular networks and addresses Base Stations (BS) and User Equipment (UE) for these networks. Standard EN 301 is part of the 908-9 series; The Harmonized EN for IMT-2000 focuses on TDMA Single Carrier (UWC 136) (BS) and 3.2 of the R&TTE Directive. It covers the basic requirements outlined in the article.

The technical requirements of the present document are valid within the scope of the environmental profile for the operation of the equipment to be declared by the supplier. The equipment shall always comply with all technical requirements of the current document while operating within the limit limits of the declared operational environmental profile.

The transmitter emission mask is defined as the attenuation requirements of off-channel RF energy. This out-of-band emission is the result of the carrier modulation process, noise, and filtering artifacts. The relevant emissions are those that fall into the immediately adjacent first or second alternative channels.

Conducted harmonic and spurious emissions are emissions measured at the antenna terminal at a frequency or frequencies outside the allowable bandwidth of the transmitter. Reducing the level of these spurious emissions is necessary to prevent harmful interference and will not affect the quality of the transmitted information.

Transmitter intermodulation products transmitted at antenna terminals are created by mixing the output of one channel transmitter with the output of other channels. The generation of these spurious emissions will not affect the quality of the transmitted information. The overall transmitter intermodulation performance shall take into account all transmitter coupling and isolation equipment.

The receiver's intermodulation spurious response attenuation is a measure of its ability to receive a modulated input RF signal frequency in the presence of a modulated signal and an unmodulated signal; They are separated by the nth order from each other and from the assigned input signal frequency. Unwanted mixing of the two signals may occur in the receiver's nonlinear elements, producing a third signal whose frequency is equal to the assigned input RF signal frequency.
