SIST ETS 300 086:1998 is the Slovenian edition of ETS 300 086 Edition 1 from ETSI. It specifies technical characteristics and test conditions for land mobile radio equipment with an internal or external RF connector, intended primarily for analogue speech, so manufacturers, test laboratories and approval bodies can assess base stations, mobile stations and handportable stations in a consistent way.

What does SIST ETS 300 086:1998 specify?

SIST ETS 300 086:1998 covers the minimum characteristics needed for angle modulation radio equipment in the land mobile service, operating between 30 MHz and 1000 MHz with 12.5 kHz, 20 kHz or 25 kHz channel separations. The scope focuses on equipment with a 50 Ω antenna connection or an internal 50 Ω RF connector that allows conducted testing.

The standard applies to these equipment types:

• base stations
• mobile stations
• handportable stations with an antenna socket
• handportable stations with an integral antenna, provided they have a permanent or temporary internal 50 Ω RF connector for testing

It does not extend to handportable equipment that has neither an external nor an internal RF connector, and no way to add a temporary internal 50 Ω RF connector.

The document is organized into clauses 1 to 10 and three annexes.

Annex	What it covers
Annex A	Radiated measurements, test sites and anechoic chamber guidance
Annex B	Specifications for adjacent channel power measurement arrangements
Annex C	Graphic selection of equipment and frequencies for testing single- and multi-channel equipment

What are the key requirements of SIST ETS 300 086:1998?

SIST ETS 300 086:1998 is built around representative type testing: the equipment submitted for approval must meet the standard on all intended channels, but the standard gives a controlled way to choose samples and frequencies so every channel does not need to be measured separately. That matters in practice because it lets laboratories test efficiently while still covering the operating range.

Test presentation and sampling

Clause 3 sets how equipment is presented for testing. It covers model choice for type approval, alignment range and switching range, the AR1 and AR2 categories, choice of frequencies, and the handling of single-channel, two-channel and multi-channel equipment.

For equipment without an external 50 Ω RF connector, clause 3.1.12 and Annex C guide how testing is done through a temporary or internal connector. This is important for integral-antenna products, because the test setup must still give access to transmitter output and receiver input.

Mechanical and electrical design

Clause 3.2 covers general design points, controls, transmitter shut-off facility and marking. Clause 6.4 and 6.7 say that automatic transmitter shut-off and receiver mute or squelch are made inoperative during type tests.

In practice, this keeps safety or convenience functions from masking real performance during approval testing. Clause 6.8 also requires the rated audio output power to be declared by the manufacturer and measured with a resistive load that simulates normal operation.

Transmitter characteristics

Clause 4.1 sets the transmitter limits and clause 7 gives the methods for checking them. The main transmitter parameters are frequency error, carrier power, effective radiated power, frequency deviation, adjacent channel power, spurious emissions, intermodulation attenuation and transient frequency behaviour.

For equipment without an external antenna connector, effective radiated power is measured radiated rather than conducted. For base stations, intermodulation attenuation is specifically required, and clause 7.7 uses a directional coupler and spectrum analyser arrangement to check how well the transmitter resists unwanted mixing products.

The frequency deviation requirements also control how the transmitter behaves with higher audio modulation frequencies. In practice, this limits unwanted widening of the transmitted signal and helps protect adjacent channels.

Receiver characteristics

Clause 4.2 sets the receiver limits and clause 8 provides the corresponding methods. The receiver checks include maximum usable sensitivity, amplitude characteristic, co-channel rejection, adjacent channel selectivity, spurious response rejection, intermodulation response rejection, blocking or desensitisation, and spurious radiations.

This is the part that shows whether a receiver can hear a wanted signal in the presence of interference. Clause 8.1 uses the SND/ND ratio for conducted sensitivity, while clause 8.2 uses field strength for equipment without an external antenna connector.

Clause 8.6 is important because it maps out spurious response search and measurement across the relevant frequency ranges. For purchasers and engineers, this tells you how resistant the receiver is to false responses caused by local oscillator harmonics and other internal frequencies.

Duplex operation

Clause 4.3 and clause 9 add requirements for duplex operation, where transmission and reception happen at the same time. The standard requires additional checks for receiver desensitisation and receiver spurious response rejection with a duplex filter or with two antennas.

That matters for equipment designed for simultaneous transmit and receive, because the transmitter must not overload the receiver path during normal use.

Test conditions and uncertainty

Clauses 5 and 6 define normal and extreme test conditions, power sources, ambient temperatures, test modulation, artificial antenna use and arrangements for transmitter and receiver test signals. Clause 5.5 requires thermal balance before extreme-temperature measurements.

Clause 3.3 and clause 10 make measurement uncertainty part of the result. The uncertainty must be reported for each parameter and kept within the maximum values given in the standard, with the values used at a 95% confidence level. In practice, that makes test reports comparable across laboratories.

What terms does SIST ETS 300 086:1998 define?

• Base station - equipment fitted with an antenna socket for use with an external antenna in a fixed location.
• 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.
• Handportable station - equipment normally used on a stand-alone basis, carried on a person or held in the hand, with an antenna socket or an integral antenna.
• Integral antenna - an antenna that is part of the equipment and is connected without a 50 Ω external connector.
• Angle modulation - either phase modulation (G3) or frequency modulation (F3).
• Conducted measurements - measurements made through a direct 50 Ω connection to the equipment under test.
• Radiated measurements - measurements based on the absolute level of a radiated field.
• SND/ND - signal + noise + distortion divided by noise + distortion, used in receiver sensitivity testing.

Who uses SIST ETS 300 086:1998?

SIST ETS 300 086:1998 is used by manufacturers of land mobile radio equipment, accredited test laboratories, type approval bodies and regulatory authorities. It is relevant for engineers working on base stations, mobile stations and handportable stations intended for analogue speech.

Quality managers and compliance teams use it to plan type testing, define test samples, prepare reports and check that the measured performance matches the approval requirements. Buyers and specifiers use it to compare equipment families on a common technical basis.

What changed in SIST ETS 300 086:1998 from the previous edition?

SIST ETS 300 086:1998 is identical to ETS 300 086 Edition 1.

Which standards are used with SIST ETS 300 086:1998?

• CEPT Recommendation T/R 24-01 - named in the foreword as the basis for the standard.
• EMC Directive 89/336 EEC - referenced for radiated emissions below 30 MHz, where supporting specifications are expected.
• ETSI technical report on guidelines for estimating uncertainties in measuring methods - mentioned as the future reference for uncertainty treatment.
• Additional standards or specifications may also be needed for equipment intended for connection to the public switched telephone network (PSTN).

What does the SIST ETS 300 086:1998 document contain?

The document contains the full measurement framework for approval testing: transmitter methods in clause 7, receiver methods in clause 8, duplex-operation checks in clause 9, and measurement uncertainty in clause 10. It also includes figure-based test templates for frequency deviation and transient frequency behaviour, plus a detailed intermodulation measurement arrangement.

Annex A gives the radiated test site guidance, including outdoor arrangements and an optional anechoic chamber setup. Annex B specifies the power measuring receiver used for adjacent channel power work and includes tables for attenuation points and frequency displacement. Annex C gives a graphic aid for selecting equipment and frequencies during testing of single- and multi-channel equipment.

The standard is therefore a test and conformity document, not a product design guide. It tells laboratories what to measure, how to set up the tests and how to interpret the reported results for land mobile speech radio equipment.

Foreword
This European Telecommunication Standard has been prepared by the Radio Equipment and Systems
(RES) Technical Committee of the European Telecommunications Standards Institute (ETSI). The draft
has undergone the ETSI public enquiry process, and is now published.
The standard which is based upon CEPT Recommendation T/R 24-01, is a general standard which may be
superseded by specific standards covering specific applications.
Angle modulation shall be used for radio equipment covered by this standard, but individual national
administrations are free to choose the type of modulation. Channel separations, temperature range,
maximum transmitter output power/effective radiated power, class of transmitter intermodulation
attenuation and the inclusion of automatic transmitter shut-off facility may all be conditions attaching to the
issue of a licence by the appropriate administration.
Additional standards or specifications may be required for equipment such as that intended for connection
to the public switched telephone network (PSTN).
This standard 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 provides 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 3.1, referring to the presentation of
equipment for testing purposes.
Introduction
This standard 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 4 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 3.3.
This standard 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 standard contains instructions for the presentation of equipment for type testing purposes (clause 3),
conditions (clause 5) and measurement methods (clauses 7 and 8).
This standard 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,
- if equipment available on the market is required to be checked it shall be tested in
accordance with the methods of measurement specified in this standard.
This standard covers base stations, mobile stations and two categories of handportable stations. One
category is fitted with a 50 Πexternal antenna socket or connector. The other category has no external
antenna socket, but:
- either it is fitted with a permanent internal 50 ΠRF connector,

Page 8
ETS 300 086: January 1991
- or it can be fitted with a temporary internal 50 ΠRF connector,so that conducted
measurements can be performed.
The means to access and/or implement the internal connector shall be provided by the manufacturer.
Details of the means used during type testing shall be provided by the accredited test laboratory with the
test report, subclause 3.1.12.

ETS 300 086: January 1991
1 Scope
This standard 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 angle modulation
systems for use in the land mobile service, operating on radio frequencies between 30 MHz and
1000 MHz, with channel separations of 12.5 kHz, 20 kHz and 25 kHz, and intended primarily for analogue
speech.
In this standard 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 standard 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 ΠR.F. 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:
- Transmitter effective radiated power
- Transmitter radiated spurious emissions
- Receiver maximum usable sensitivity (field strength)
- Receiver radiated spurious emissions
Handportable equipment without an external or internal RF connector and without the possibility of having a
temporary internal 50 ΠRF connector is not covered by this standard.
2 Definitions, abbreviations and symbols
2.1 Definitions
For the purpose of this standard, the following definitions apply:
Base station: equipment fitted with an antenna socket, for use with an external antenna, and intended for
use in a fixed location.

3 General
3.1 Presentation of equipment for testing purposes
Each equipment submitted for type testing shall fulfil the requirements of this standard 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 standard, on samples of equipment defined in
subclause 3.1.1 to 3.1.12.
These clauses are intended to give confidence that the requirements set out in this standard have been
met without the necessity of performing measurements on all channels.

ETS 300 086: January 1991
3.1.1 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 must be identical in all respects with the preliminary model tested.
In the case of handportable equipment without a 50 Πexternal antenna connector, see subclause 3.1.12.
3.1.2 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.
3.1.3 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.

3.2 Mechanical and electrical design
3.2.1 General
The equipment submitted by the manufacturer, or his representative, shall be designed, constructed and
manufactured in accordance with sound engineering practice, and with the aim of minimising harmful
interference to other equipment and services.
3.2.2 Controls
Those controls which if maladjusted might increase the interfering potentialities of the equipment shall not
be accessible to the user.
3.2.3 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.
3.2.4 Marking
The equipment shall be marked in a visible place. This marking shall be legible, tamperproof and durable.
The marking shall include:
- the name of the manufacturer or his trade mark
- the type number of designation and serial number
- the type approval number (when allocated by appropriate authorities).
3.3 Interpretation of the measurement results
The interpretation of the results recorded in a test report for the measurements described in this standard
shall be as follows.
The measured value related to the corresponding limit will be used to decide whether an equipment meets
the requirements of the standard.
The measurement uncertainty value for the measurement of each parameter shall be included in the test
report.
The recorded value of the measurement uncertainty shall be, for each measurement, equal to or lower
than the figures in subclause 10 (table of measurement uncertainty).
NOTE: This procedure for using Maximum Acceptable Uncertainty values is valid until
superseded by other appropriate publications of ETSI covering this subject.
The use of the measured value has been chosen because there is no other ETSI
standard covering the subject at the time of publication of this standard. Therefore the
measurement uncertainty shall be used as a quality of the actual measurement. The
Measurement Uncertainty values can also be used by Accreditation Authorities during
their accreditation procedures to ensure compliance/conformity with the requirements
of type testing to ETSI Standards.
