Introduction
This ETS was drafted on the assumption that:
- the type test measurements performed in an accredited test laboratory in one country would be
accepted by the Type Approval Authority in another country provided that the national regulatory
requirements are met;
- if equipment available on the market is required to be checked it should be tested in accordance
with the methods of measurement specified in this ETS.

1 Scope
This ETS 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. Clause 5 provides the
corresponding limits. These limits have been chosen to ensure an acceptable grade of service and to
minimise harmful interference to other equipment and services. They are based on the interpretation of the
measurement results described in subclause 4.3.
This ETS covers the minimum characteristics considered necessary in order to make the best 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. It 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.
This ETS is based upon CEPT Recommendation T/R 24-01 annex III [1], and is a general standard which
may be superseded by specific standards covering specific applications.
In this ETS different requirements are given for the different radio frequency bands, channel separations,
environmental conditions and types of equipment, where appropriate.
The measurement methods have been adapted from ETR 027 [3] where possible.
The type of equipment covered by this ETS is handportable stations with integral antennas.
This ETS 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.
This ETS is complementary to ETS 300 086 [2] 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.
Equipment which also includes an external or internal RF connector should be type tested to the
requirements of ETS 300 086 [2] using this connector.
Additional standards or specifications may be required for equipment such as that intended for connection
to the Public Switched Telephone Network (PSTN).
This ETS does not cover requirements for radiated emissions below 30 MHz.
This ETS may also be used by accredited test laboratories for the assessment of the performance of the
equipment. The performance of the equipment submitted for type testing should be representative for the
performance of the corresponding production model. In order to avoid any ambiguity in that assessment,
this ETS contains instructions for the presentation of equipment for type testing purposes (clause 4),
conditions (clause 6) and measurement methods (clauses 8 and 9).

3 Definitions, abbreviations and symbols
3.1 Definitions
For the purpose of this ETS, the following definitions apply:
angle modulation: Either phase modulation (G3) or frequency modulation (F3).
audio frequency load: The 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: The 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 agreed between the manufacturer and the testing laboratory and details included in the test
report. If special equipment is required then it should be provided by the manufacturer.
band-stop filter (for the SINAD meter): The 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: An 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: The psophometric weighting network is described in CCITT
Recommendation Blue Book O.41 [5].

Page 11
ETS 300 296: December 1994
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:
full tests: In all cases except where qualified as "limited", tests are performed according to this
ETS.
limited tests: The limited tests, subclause 4.1, are as follows:
- receiver average usable sensitivity (field strength), subclause 9.1;
- receiver adjacent channel selectivity, subclause 9.4;
- transmitter frequency error, subclause 8.1;
- transmitter effective radiated power, subclause 8.2;
- transmitter adjacent channel power, subclause 8.4.

4 General
4.1 Presentation of equipment for testing purposes
Each equipment submitted for type testing shall fulfil the requirements of this ETS on all channels over
which it is intended to operate.
To simplify and harmonise the type testing procedures between the different test laboratories,
measurements shall be performed, according to this ETS, on samples of equipment defined in subclauses
4.1.1 to 4.1.11.
These clauses are intended to give confidence that the requirements set out in this ETS have been met
without the necessity of performing measurements on all channels.
4.1.1 Choice of model for type approval
The manufacturer shall provide one or more production model(s) of the equipment, as appropriate, for type
approval testing.
If type approval is given on the basis of tests on a preliminary model, then the corresponding production
models shall be identical in all respects with the preliminary model tested.
4.1.2 Definitions of alignment range and switching range
The manufacturer shall, when submitting equipment for test, state the alignment ranges for the receiver
and the transmitter.
The alignment range is defined as the frequency range over which the receiver and the transmitter can be
programmed and/or realigned to operate, without any physical change of components other than
programmable read only memories or crystals (for the receiver and the transmitter).
The manufacturer shall also state the switching range of the receiver and the transmitter (which may
differ).
The switching range is the maximum frequency range over which the receiver or the transmitter can be
operated without reprogramming or realignment.
For the purpose of all measurements, the receiver and transmitter shall be considered separately.
4.1.3 Definition of the categories of the alignment range (AR1 and AR2)
The alignment range falls into one of two categories.
The first category corresponds to a limit of the alignment range, of the receiver and the transmitter, which
is less than 10 % of the highest frequency of the alignment range for equipment operating on frequencies
up to 500 MHz, or less than 5 % for equipment operating above 500 MHz. This category is defined as
AR1.
The second category corresponds to an alignment range of the receiver and transmitter which is greater
than 10 % of the highest frequency of the alignment range for equipment on frequencies up to 500 MHz, or
greater than 5 % for equipment operating above 500 MHz. This category is defined as AR2.
4.1.4 Choice of frequencies
The frequencies for testing shall be chosen by the manufacturer in consultation with the appropriate
authority, in accordance with subclauses 4.1.5 to 4.1.11 and annex C. The manufacturer selects the
frequencies for testing and will ensure that the chosen frequencies are within one or more of the national
bands for which type approval is required.

This clause contains the limit values of the parameters defined in clauses 8 and 9.
5.1 Transmitter parameter limits
5.1.1 Frequency error
For the definition and the measuring method see subclause 8.1.
The frequency error shall not exceed the values given in table 1 under normal, extreme or any intermediate
set of conditions.
For practical reasons the measurements will be performed only under normal and extreme test conditions
as stated in subclause 8.1.

NOTE: For handportable stations having integral power supplies, the figures given in the
table only apply to the limited temperature range 0°C to +30°C. However for the
full extreme temperature conditions (subclause 6.4.1) exceeding the limited
temperature range above, the following frequency error limits apply:
± 2,50 kHz between 300 MHz and 500 MHz;
± 3,00 kHz between 500 MHz and 1 000 MHz.
5.1.2 Effective radiated power
For the definition and the measuring method see subclause 8.2.
The maximum effective radiated power under normal test conditions shall be within d from the rated
f
maximum effective radiated power.
The average effective radiated power under normal test conditions shall also be within d from the rated
f
average effective radiated power.
