Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [4] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Council Directive on the approximation of the laws of
the Member States relating to electromagnetic compatibility ("the EMC Directive") (89/336/EEC [3] as amended) and
Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and
telecommunications terminal equipment and the mutual recognition of their conformity ("the R&TTE Directive" [2]).
The present document is part 4 of a multi-part deliverable. Full details of the entire series can be found in part 1 [1].

1 Scope
The present document, together with 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.
Examples of Fixed Radio Links equipment are given in annex A.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and 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.
The environmental classification and the emission and immunity requirements used in the present document are as
stated in EN 301 489-1 [1], except for any special conditions included in the present document.

following apply:
CHannel Separation (CHS): According to ITU-R Recommendation F.1191-1 [5], the CHannel Separation (CHS) is
taken as XS/2 for alternated frequency channel arrangements and XS for co-channel and interleaved frequency channel
arrangements as defined by ITU-R Recommendation F.746-3 [6], 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

4 Test conditions
For the purposes of the present document, the test conditions of EN 301 489-1 [1], clause 4, shall apply as appropriate.
Further product related test conditions for fixed radio links are specified in the present document.
4.1 General
For emission and immunity tests the test modulation, test arrangements, etc., as specified in the present document,
clauses 4.1.1 to 4.3.2, shall apply.
4.1.1 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
