3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI EN 301 489-1 [1] and the following
apply:
Base Station (BS): alternative name for Central Station
Central Station (CS): which can be subdivided into two units:
• the exchange unit, also called Central Controller Station (CCS) - (interface to the local switch); and
• the radio unit, also called Central Radio Station (CRS) - (central base band/radio transceiver)
NOTE: In some deployments the term Base Station is also used in place of Central Station. For the purposes of
the present standard either terms are assumed and are completely interchangeable.
CHannel Separation (CHS): CHannel Separation (CHS) is taken as XS/2 for alternated frequency channel
arrangements according to Recommendation ITU-R F.1191-1 [i.3] and XS for co-channel and interleaved frequency
channel arrangements as defined by Recommendation ITU-R F.746-3 [i.4], XS is the radio-frequency separation
between the centre frequencies of adjacent radio-frequency channels on the same polarization and in the same direction
of transmission.
operating frequency range: range(s) of radio frequencies covered by the Equipment Under Test (EUT) without any
change of units
Repeater Station (RS): radio repeater outstations with or without subscriber interfaces
Terminal station (TS): outstations with subscriber interfaces

4 Test conditions
4.1 General
4.1.1 Introduction
For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4, apply as appropriate.
Further product related test conditions for fixed radio links are specified in the present document.
For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document,
clauses 4.1.2 to 4.3.2, shall apply.
4.1.2 Test conditions and configurations
This clause defines the test conditions and configurations for the emission and immunity tests as follows:
• a transmitter shall, as a minimum, comprise the element between E' and A' of figure 1. Additionally the
transmitter may comprise any of the other elements from the transmitter chain shown in figure 1. If these
additional elements are part of the transmitter or system they shall also meet the requirements of the present
document;

• a transceiver shall comprise as a minimum the elements E' to A' and A to E shown in figures 1 and 2, and
additionally it may comprise any combinations of the other elements. If these additional elements are part of
the transceiver they shall also meet the requirements of the present document;
• the equipment shall be tested under conditions which are within the manufacturer's declared range of humidity,
temperature and supply voltage;
• the test configuration shall be as close to normal intended use as possible;
• if the equipment is part of a system, or can be connected to ancillary equipment, then it shall be acceptable to
test the equipment while connected to the minimum configuration of ancillary equipment necessary to exercise
the ports;
• ports which in normal operation are connected to ancillary or other equipment shall be either connected to
such equipment, or to a representative termination to simulate the input/output characteristics of the ancillary
or other equipment. Radio Frequency (RF) input/output ports shall be correctly terminated;
• if the equipment has a large number of ports, then a sufficient number shall be selected to simulate actual
operation conditions and to ensure that all the different types of termination are tested;
• ports which are not connected to cables during normal intended operation, e.g. service connectors,
programming connectors, temporary connectors etc. shall not be connected to any cables for the purpose of
ElectroMagnetic Compatibility (EMC) testing. Where cables have to be connected to these ports, or
interconnecting cables have to be extended in length in order to exercise the EUT, precautions shall be taken to
ensure that the evaluation of the EUT is not affected by the addition or extension of these cables;
• the test conditions, test configuration and mode of operation shall be recorded in the test report.
4.1.3 Emission tests
The provisions ETSI EN 301 489-1 [1], clause 8 shall apply with the following modification.
For Point-to-Multipoint systems a communications link shall be established, which shall comprise of the Central Station
and a minimum of one Terminal Station. These stations are tested separately.
4.1.4 Immunity tests
The provisions of ETSI EN 301 489-1 [1], clause 9.1 shall apply with the following modifications.
The test configuration shall for transmitters be in accordance with the principle of figure 3, and for receivers it shall be
in accordance with the principle of figure 4, and for transceiver shall be in accordance with the principle of figure 5.
The measuring equipment shall be located outside the test environment. Adequate measures shall be taken to avoid any
effects of the unwanted signals on the measuring equipment.

apply:
Base Station (BS): alternative name for Central Station
Central Station (CS): which can be subdivided into two units:

1 Scope
The present document, together with ETSI EN 301 489-1 [1], covers the assessment of Fixed Radio Links, and ancillary
equipment in respect of ElectroMagnetic Compatibility (EMC).
Technical specifications related to the antenna port of the radio equipment are not included in the present document.
Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum.
The present document specifies the applicable test conditions, performance assessment and performance criteria for
Analogue and Digital Fixed Radio Links operating as fixed Point-to-Point, and Point-to-Multipoint systems as defined
in annex B, including the associated ancillary equipment.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and ETSI EN 301 489-1 [1], the provisions of the present document take precedence.
The processing and protection switch, (de)modulator, transmitter, receiver, RF filters, branching networks, feeders are
covered by the present document. The multiplexing and/or de-multiplexing elements are covered if they form part of the
transmitter, receiver and/or transceiver.
