Foreword
This Interim European Telecommunication Standard (I-ETS) has been prepared by the Radio Equipment
and Systems (RES) Technical Committee, and having passed through the Voting phase of the ETSI
standards approval procedure, is now published.
This I-ETS is based upon CEPT Recommendation T/R 24-01 Annex V [1].
For combined speech/non-speech equipment this I-ETS is complementary to ETS 300 086 [2], which
covers radio equipment for use in the land mobile service intended primarily for analogue speech. Limits
stated in this I-ETS are in line with ETS 300 086 [2]. However it is anticipated that figures for limits for
receiver sensitivity (field strength) will be revised.
Angle modulation with constant envelope should be used for radio equipment covered by this I-ETS.
Channel separations, temperature range, maximum transmitter output power/effective radiated power and
the type and characteristics of modulation, class of transmitter intermodulation attenuation and the inclusion
of automatic transmitter shut-off facility may be conditions required for the issue of a licence by the
appropriate regulatory authority.
Additional standards or specifications may be required for some equipment i.e. such as that intended for
connection to the Public Switched Telephone Network (PSTN).
It should be noted that radio equipment for data is covered by I-ETS 300 113 [3].
This I-ETS does not cover requirements for radiated emissions below 30 MHz. It is anticipated that
methods of measurements and minimum standards for such emissions will be covered by specifications
supporting EMC Directive 89/336 EEC.
Annex A contains normative specifications and additional information concerning radiated measurements.
Annex B contains normative specifications for adjacent channel power measurement arrangements.
Annex C is a graphic representation of the normative subclause 5.1, referring to the presentation of
equipment for testing purposes.
The means of system identification for non-speech equipment, or the non-speech part of combined
speech/non-speech equipment, should be approved by the appropriate national regulatory authority.
Introduction
This I-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 6 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 5.3.
This I-ETS will 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 shall be representative for the
performance of the corresponding production model. In order to avoid any ambiguity in that assessment,
this I-ETS contains instructions for the presentation of equipment for type testing purposes (Clause 5),
conditions (Clauses 7 and 8) and measurement methods (Clauses 9 and 10).
This I-ETS was drafted on the assumption that:
- the type test measurements will be performed only once, in one of the accredited test laboratories,
and the measurements accepted by the various authorities in order to grant type approval;

Page 8
I-ETS 300 219: October 1993
- 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 I-ETS.
This I-ETS covers base stations, mobile stations and two categories of handportable stations. One
category is fitted with a 50 Ω external antenna socket or connector. The other category has no external
antenna socket, but either:
- it is fitted with a permanent internal 50 Ω RF connector; or
- it can be fitted with a temporary internal 50 Ω RF connector, so that conducted measurements can
be performed.
The means to access and/or implement the internal connector should be provided by the manufacturer.
Details of the means used during type testing should be recorded by the accredited test laboratory in the
test report (see subclause 5.1.12).

I-ETS 300 219: October 1993
1 Scope
This I-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 non-speech and
to the non-speech part of combined speech/non-speech constant envelope angle modulated equipment for
use 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.
In this I-ETS, a non-speech radio equipment is defined as a radio equipment transmitting a signal to initiate
a specific response in the receiver. The equipment shall comprise of a transmitter and associated encoder
and/or a receiver and associated decoder. The encoder and/or decoder may be a separate piece of
equipment, in which case compliance to this I-ETS covers the encoder and/or decoder in connection with
the transmitter and/or receiver equipment.
In this I-ETS different requirements are given for the different radio frequency bands, channel separations,
environmental conditions and types of equipment, where appropriate.
The types of equipment covered by this I-ETS are as follows:
- Base station: equipment fitted with an antenna socket;
- Mobile station: equipment fitted with an antenna socket;
- Handportable stations:
a) fitted with an antenna socket; or
b) without an external antenna socket (integral antenna equipment) but fitted with a permanent
internal or a temporary internal 50 Ω RF connector which allows access to the transmitter
output and the receiver input.
For the type of equipment defined in b), the additional measurements which shall be made using the
equipment antenna connected to the station (and not using any connector) are as follows:
- subclause 9.3: Transmitter effective radiated power;
- subclause 9.5.4: Transmitter radiated spurious emissions;
- subclause 10.3: Receiver maximum usable sensitivity (response, field strength);
- subclause 10.9.4: Receiver radiated spurious radiations.
Handportable equipment without an external or internal RF connector and without the possibility of having a
temporary internal 50 Ω RF connector is not covered by this I-ETS.
In the case of combined speech/non-speech equipment the speech part shall be tested to ETS 300 086 [2]
and additionally the tests described in the following subclauses of this I-ETS shall be carried out:
- subclause 9.4: Adjacent channel power;
- subclause 10.2: Maximum usable sensitivity (responses,conducted);
- subclause 10.3: Maximum usable sensitivity (responses, field strength).
These requirements also apply for equipment with an analogue output facility provided for test purposes
only.
Where an equipment has already been type approved to ETS 300 086 [2], and is resubmitted for type
testing to this I-ETS, additionally the tests described in the following subclauses of this I-ETS shall be
carried out:
- subclause 9.4: Adjacent channel power;

Page 10
I-ETS 300 219: October 1993
- subclause 10.2: Maximum usable sensitivity (responses, conducted);
- subclause 10.3: Maximum usable sensitivity (responses, field strength);
- subclause 9.5: Spurious emissions.

5 General
5.1 Presentation of equipment for testing purposes
Each equipment submitted for type testing shall fulfil the requirements of this I-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 I-ETS, on samples of equipment defined in
subclauses 5.1.1 to 5.1.12.
These subclauses are intended to give confidence that the requirements set out in this I-ETS have been
met without the necessity of performing measurements on all channels.
5.1.1 Choice of model for type testing
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 must be identical in all respects with the preliminary model tested.

5.1.3 Definition of the categories of the alignment range (AR1 and AR2)
The alignment range falls into one of two categories.
a) 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.
b) 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.
5.1.4 Choice of frequencies
The frequencies for testing shall be chosen by the manufacturer in consultation with the appropriate
authority, in accordance with subclauses 5.1.5 to 5.1.11 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.

of the alignment range. The frequency of the upper channel shall be within 100 kHz of the highest
frequency of the switching range and the frequency of the lower channel shall be within 100 kHz of the
lowest frequency of the switching range.
Full tests shall be carried out on the centre channel and limited tests (see Clause 3) on the upper and
lower channel.
The frequency of one of the channels of the second sample shall be within 100 kHz of the highest
frequency of the alignment range.
Full tests shall be carried out on this channel.
The frequency of one of the channels of the third sample shall be within 100 kHz of the lowest frequency of
the alignment range.
Full tests shall be carried out on this channel.
5.1.11 Testing of multi channel equipment (more than two channels) of category AR2
(switching range equals the alignment range)
In the case of multi channel equipment of the category AR2, with switching range equal to the alignment
range one sample of the equipment shall be tested.
The centre frequency of the switching range of the sample shall correspond to the centre frequency of the
alignment range.
Full tests shall be carried out on a frequency within 100 kHz of the centre frequency of the switching range
and within 100 kHz of the lowest and also within 100 kHz of the highest frequency of the switching range.
5.1.12 Testing of equipment without an external 50 ΩΩ RF connector
5.1.12.1 Equipment with an internal permanent or temporary antenna connector
The means to access and/or implement the internal permanent or temporary antenna connector shall be
stated by the manufacturer with the aid of a diagram.
The fact that use has been made of the internal antenna connection to facilitate measurements shall be
recorded in the test report.
5.1.12.2 Equipment with a temporary antenna connector
The manufacturer, or an authorised representative, may submit one set of equipment with the normal
antenna connected, to enable the radiated measurements to be made.
The manufacturer, or an authorised representative, shall attend the test laboratory at conclusion of the
radiated measurements, to disconnect the antenna and fit the temporary connector.
The test laboratory staff shall not connect or disconnect any temporary antenna connector.
