Introduction
The present document is intended to specify the minimum performance and the methods of measurement of radio
equipment for use in the land mobile service as specified in the scope.
The present document is based on ETS 300 296, which covers analogue radio equipment intended primarily for the
transmission of speech for use in the Land Mobile Radio service and having an integral antenna.
Equipment similar to that covered by the present document, but having an RF connector is covered by ETS 300 086 (for
details, see the scope of the present document as well as the scope of ETS 300 086).
Equipment intended to transmit signals to initiate a specific response is covered by EN 300 219 (for details, see the
scope of the present document as well as the scope of EN 300 219), or by ETS 300 341 in the case of integral antenna
equipment (for details, see the scope of the present document as well as the scope of ETS 300 341).
Equipment intended for the transmission of data is covered by ETS 300 113 (for details, see the corresponding scope),
or by ETS 300 390 in the case of integral antenna equipment (for details, see the corresponding scope).
Requirements to be fulfilled by equipment designed to meet several standards can be found in Part 1,clause 4 of
standards such as ETS 300 341 and/or ETS 300 390 as appropriate.
Angle modulation is used for radio equipment covered by the present document, but individual national administrations
are free to choose the type of modulation. Channel separations, maximum transmitter output power/effective radiated
power and the inclusion of automatic transmitter shut-off facility may all be conditions relating to the issue of a licence
by the appropriate administration.
Annex A provides additional information concerning radiated measurements.
Annex B contains normative specifications for adjacent channel power measurement arrangements.
Annex C is a graphic representation corresponding to the selection of equipment for testing purposes.
Annex D contains specifications for the test discriminator used in transient measurements.
Clause 5 provides the appropriate limits. These limits have been chosen to ensure an acceptable grade of service and to
minimize harmful interference to other equipment and services. They are based on the interpretation of the
measurement results described in clause 4.3.
Provision for the placing on the market of radio equipment in EU Member States can be found in the R&TTE Directive
(Directive 99/5/EC [1]). It can also be noted that some of the parameters considered as essential under the
R&TTE Directive [1] had already been listed as essential under the EMC Directive.
The present document may also be used in CEPT Countries that are not EU Member States. For the benefit of these
Countries, mechanisms for mutual recognition of type approval have been identified in Decision ERC/DEC/(97)10.
Alternatively, another approach may be used in Countries that have not implemented this Decision: type test
measurements performed in an accredited test laboratory in one country would be accepted by the Administration in
another country provided that the national regulatory requirements are met (CEPT recommendation ERC/REC 01-06).
Decision ERC/DEC/(97)10 also addresses issues related to total quality management.
The present document may, in particular, be used by accredited test laboratories for the assessment of the performance
of the equipment. The performance of the equipment, in the case of conformity assessment measurements, shall be
representative for the performance of the corresponding production model. In order to avoid any ambiguity in that
assessment, the present document contains general instructions (clause 4), conditions (clauses 6 and 7) and methods of
measurement (clauses 8 and 9).
The present document was drafted on the assumption that if equipment available on the market is required to be
checked, it should be tested in accordance with the methods of measurement specified in the present document.

1 Scope
The present document covers the minimum characteristics considered necessary in order to avoid harmful interference and
to make acceptable use of the available frequencies. It does not necessarily include all the characteristics which may be
required by a user, nor does it necessarily represent the optimum performance achievable.
The present document applies to equipment with integral antennas, used in angle modulation systems in the land mobile
service, operating on radio frequencies between 30 MHz and 1 000 MHz, with channel separations of 12,5 kHz, 20 kHz
and 25 kHz, and is intended primarily for analogue speech.
The present document is based upon ETS 300 296, and is a general standard, the provisions of which may be superseded in
whole or in part by specific standards for specific applications.
In the present document different requirements are given for the different radio frequency bands, channel separations,
environmental conditions and types of equipment, where appropriate.
The type of equipment covered by the present document is handportable stations with integral antennas.
The present document covers angle modulation to be used for radio equipment, but individual national administrations are
free to choose the type of modulation. Channel separations, maximum transmitter output power/effective radiated power
and the inclusion of automatic transmitter shut-off facility may all be conditions attaching to the issue of a licence by the
appropriate administration.
The present document is complementary to ETS 300 086, which covers radio equipment with an internal or external RF
connector, for use in the land mobile service. It is primarily intended for omnidirectional applications.
Additional standards or specifications may be required for equipment such as that intended for connection to the Public
Switched Telephone Network (PSTN).

3 Definitions, abbreviations and symbols
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
angle modulation: either phase modulation (G3) or frequency modulation (F3)
audio frequency load: audio frequency load is normally a resistor of sufficient power rating to accept the maximum audio
output power from the equipment under test. The value of this resistor should be that stated by the manufacturer and equal
to the impedance of the audio transducer at 1 000 Hz. In some cases it may be necessary to place an isolating transformer
between the output terminals of the receiver under test and the load
audio frequency termination: audio frequency termination is any connection other than the audio frequency load which
may be required for the purpose of testing the receiver. The termination device should be, as appropriate, either chosen by
the manufacturer or agreed between the manufacturer and the testing laboratory and details included in test reports. If
special equipment is required then it should be provided by the manufacturer
band-stop filter (for the SINAD meter): characteristics of the band-stop filter used in the audio distortion factor meter
and SINAD meter should be such that at the output the 1 000 Hz tone will be attenuated by at least 40 dB and at 2 000 Hz
the attenuation will not exceed 0,6 dB. The filter characteristic shall be flat within 0,6 dB over the ranges 20 Hz to 500 Hz
and 2 000 Hz to 4 000 Hz. In the absence of modulation the filter must not cause more than 1 dB attenuation of the total
noise power of the audio frequency output of the receiver under test
integral antenna: antenna designed to be connected to the equipment without the use of a 50 Ω external connector and
considered to be part of the equipment. An integral antenna may be fitted internally or externally to the equipment
psophometric weighting network: psophometric weighting network is described in ITU-T Recommendation O.41 [6]
Types of measurements:
- conducted measurements: measurements which are made using a direct connection to the equipment under test;
- radiated measurements: measurements which involve the absolute measurement of a radiated field.
Types of station:
- base station: equipment fitted with an antenna socket, for use with an external antenna and intended for use in a
fixed location;
- handportable station: equipment either fitted with an antenna socket or an integral antenna, or both, normally used
on a stand-alone basis, to be carried on a person or held in the hand;
- mobile station: mobile equipment fitted with an antenna socket, for use with an external antenna, normally used in
a vehicle or as a transportable station.
Types of tests:
-fulltests: in all cases except where qualified as "limited", tests are performed according to the present document;
-limitedtests: limited tests, as defined in EN 300 793 [2], are as follows:
- transmitter frequency error, clause 8.1;
- transmitter effective radiated power, clause 8.2;
- transmitter adjacent channel power, clause 8.4;
- receiver average usable sensitivity (field strength), clause 9.1;
- receiver adjacent channel selectivity, clause 9.4.

4.1 Selection of equipment for testing purposes
For information regarding the selection of equipment for testing purposes, refer to EN 300 793 [2].
It is expected that the usage of similar measurement methodologies will make it more likely that different laboratories
measuring the same equipment get comparable measurement results.
4.2 Mechanical and electrical design
4.2.1 General
The equipment shall be designed, constructed and manufactured in accordance with sound engineering practice, and with
the aim of minimizing harmful interference to other equipment and services.
4.2.2 Controls
Those controls which if maladjusted might increase the interfering potentialities of the equipment shall not be easily
accessible to the user.
4.2.3 Transmitter shut-off facility
When a timer for an automatic shut-off facility is operative, at the moment of the time-out the transmitter shall
automatically be switched off. The activation of the transmitter key shall reset the timer.
4.2.4 Marking
The equipment shall be marked in a visible place. This marking shall be legible, tamperproof and durable.
The marking shall be in accordance with EC Directives and/or CEPT decisions or recommendations as appropriate.
