SIST I-ETS 300 113 E1:2003 is the Slovenian adoption of ETSI I-ETS 300 113 Edition 1 for land mobile radio data equipment. It specifies technical characteristics and test conditions for non-speech and combined analogue speech/non-speech radio equipment with an internal or external antenna connector, intended for data transmission. In practice, it tells manufacturers, test labs, and approval bodies how to check transmitter and receiver performance, antenna arrangements, and test methods for type testing.
What does SIST I-ETS 300 113 E1:2003 specify?
SIST I-ETS 300 113 E1:2003 specifies the minimum technical characteristics and test conditions for data equipment used in the land mobile service. It covers equipment operating between 30 MHz and 1000 MHz with channel separations of 12,5 kHz, 20 kHz, and 25 kHz, and it focuses on constant envelope angle modulation systems for data transmission.
The standard applies to non-speech and combined analogue speech/non-speech radio equipment. It also sets special rules for equipment with an internal antenna or without an external 50 Ω RF connector, because those products need radiated measurements in addition to conducted ones.
The document is organized into scope, normative references, definitions, general test presentation, technical characteristics, test conditions, general conditions, measurement methods, duplex operation, and measurement uncertainty. It also includes annexes for radiated measurements, measurement arrangements, test-selection graphics, identification, and an access protocol.
| Annex | What it covers |
|---|---|
| Annex A | Radiated measurements and test-site arrangements |
| Annex B | Specifications for power measuring receivers, spectrum analysers, and integrating devices |
| Annex C | Graphic selection of equipment and frequencies for testing |
| Annex D | Identification code structure, timing, modulation, and field organization |
| Annex F | Access protocol, carrier sensing, observation time, and receiver timing |
What are the key requirements of SIST I-ETS 300 113 E1:2003?
SIST I-ETS 300 113 E1:2003 is built around type testing. The equipment has to meet the relevant limits across the channels on which it is intended to operate, while the sampling rules in Clause 4 are used to keep testing practical and consistent across laboratories.
Equipment presentation and test selection
Clause 4 requires a defined choice of sample and test frequencies, including rules for single-channel, two-channel, and multi-channel equipment, and special handling for equipment with an internal antenna arrangement or no external 50 Ω RF connector. This matters because the test sample has to represent the product range without forcing a full measurement on every channel.
For handportable equipment with an internal antenna, the standard adds radiated checks for transmitter effective radiated power, transmitter radiated spurious emissions, receiver maximum usable sensitivity by field strength, and receiver radiated spurious radiations. In practice, this means the antenna-integrated version must be checked as a radiating product, not only through its connector.
Transmitter performance
Clause 5.1 covers transmitter limits for frequency error, carrier power, effective radiated power, adjacent channel power, spurious emissions, intermodulation attenuation, attack time, release time, and transient behaviour. These are the main checks that show whether the transmitter stays on frequency, stays within spectrum limits, and switches on and off cleanly enough not to disturb nearby channels.
For equipment with more than one power level, the manufacturer declares the rated levels and the power control must not be accessible to the user. Measurements are then made at the lowest and highest intended power levels, which gives approval bodies a practical way to verify the full operating range.
Clause 8 adds the measurement methods. It says frequency error is measured when an unmodulated carrier is possible, carrier power is measured as conducted output power, and effective radiated power is used for equipment without an external antenna connector. It also explains how adjacent channel power, spurious emissions, and transient behaviour are measured, including time-domain and frequency-domain analysis for transmitter transients.
Receiver performance
Clause 5.2 covers receiver limits for maximum usable sensitivity, bit error rate in normal operation, co-channel rejection, adjacent channel selectivity, spurious response rejection, intermodulation response, blocking or desensitisation, spurious radiations, carrier sense delay, and receiver opening delay. These parameters show whether the receiver can recover wanted data while rejecting interfering signals and whether it behaves correctly in access protocols.
Clause 9 describes the test methods for these receiver parameters, including separate methods for continuous bit streams and for message-based operation. That distinction matters because some systems can be tested with a steady pseudorandom stream, while others only work with coded messages and need a different measurement setup.
Test conditions, power sources, and environment
Clause 6 requires both normal and extreme test conditions where stated. It defines the use of a test power source with low internal impedance, voltage measured at the equipment input, and a ±1 % tolerance during tests.
The clause also requires thermal balance before measurements at extreme temperatures and gives different procedures for continuous and intermittent operation. In practice, this means the equipment must be stabilized before approval results are taken, so the test reflects real operating behaviour rather than a warm-up transient.
General measurement conditions
Clause 7 defines how the test setup has to be arranged. The receiver input must see a 50 Ω non-reactive impedance, mute or squelch must be disabled during testing, and an artificial antenna is used as a non-radiating 50 Ω load for conducted tests.
Clause 7 also defines the normal test signals. For continuous bit streams, the standard uses fixed bit patterns and a pseudorandom sequence, plus an unwanted signal for certain tests. For non-continuous systems, the manufacturer and test authority agree a message pattern that produces the widest occupied bandwidth, and the test report must record it.
Duplex operation and measurement uncertainty
Clause 10 adds extra tests for equipment intended for duplex operation, including receiver desensitisation with simultaneous transmission and reception and receiver spurious response rejection under duplex conditions. This matters for stations that transmit and receive at the same time, because internal coupling can reduce sensitivity or create self-interference.
Clause 11 gives the measurement uncertainty limits to be used with the methods in the standard, with confidence level requirements based on ETR 028. That gives test labs a common basis for reporting results and deciding whether a measurement is close enough to a limit to matter.
What terms does SIST I-ETS 300 113 E1:2003 define?

Who uses SIST I-ETS 300 113 E1:2003?
SIST I-ETS 300 113 E1:2003 is used by manufacturers of land mobile radio data equipment, especially makers of base stations, mobile stations, and handportable stations. They use it to design products and to prepare type testing submissions.
Test laboratories and approval authorities use it to carry out or witness measurements in a repeatable way. The standard is also relevant to monitoring stations that analyze identification transmissions, and to engineering teams working on radio equipment for the land mobile service, including equipment with combined speech and data functions.
Which standards are used with SIST I-ETS 300 113 E1:2003?
SIST I-ETS 300 113 E1:2003 cites four normative references and companion documents:
- CEPT Recommendation T/R 24-01 - provides specifications for equipment used in the land mobile service.
- ETS 300 086 - covers radio equipment with an internal or external RF connector intended primarily for analogue speech, and it is used when the speech part of combined equipment has already been type approved.
- ETR 028 - gives the uncertainty method used for measurement uncertainty reporting.
- CCITT Recommendation O.153 - gives basic parameters for bit error performance measurements at bit rates below the primary rate, used for the pseudorandom bit sequence in testing.
What does the SIST I-ETS 300 113 E1:2003 document contain?
The document contains detailed measurement methods for transmitter and receiver parameters, including conducted and radiated tests, signal arrangements, and test-site guidance. Annex A describes radiated test sites and alternative indoor chamber arrangements, while Annex B specifies the receiver and analyser performance needed for the measurements.
Annex C gives graphics for choosing equipment samples and test frequencies, which helps laboratories select representative channels for single-channel, two-channel, and multi-channel equipment. Annex D provides an identification scheme with modulation options, synchronisation words, block structure, code formats, and example field organizations.
Annex F describes an access protocol with carrier sensing, observation time, initiation, and RF channel occupation rules, plus receiver timing measurements for carrier sense delay and opening delay. Together, these annexes support design verification, type testing, and technical review of land mobile data equipment.

Foreword
This Interim European Telecommunication Standard (I-ETS) has been prepared by the Radio Equipment
and Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This I-ETS has been adopted having undergone the ETSI standards approvals procedure.
This I-ETS will in future be likely to be superseded or complemented by a corresponding ETS.
This standard is based upon CEPT Recommendation T/R 24-01 [1], and is complementary to
ETS 300 086 [2], which covers radio equipment for use in the land mobile service and intended primarily
for analogue speech.
This is a general standard which may be superseded or complemented by specific standards addressing
specific applications. It applies to equipment designed to operate within the private mobile radio service
and to the associated frequency planning.
This standard is voluntary in application, however, it may be made mandatory by national administrations
as a part of the conditions attached to the issue of licenses for the use or sale of radio apparatus.
Additional standards or specifications may also be required for equipment such as that intended for
connection to the public switched telephone network (PSTN), or data networks.
Constant envelope modulation should be used. The particular type of modulation will be chosen by the
manufacturer, although it is recognized that in some countries national legislation may limit the use of
certain code structures/data formats.
Channel separations, temperature range, maximum transmitter output power/effective radiated power,
class of transmitter intermodulation attenuation and channel access timings may be conditions to the issue
of a licence by the appropriate administration.
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 standards
supporting EMC Directive 89/336/EEC.
All transmissions according to this standard should include at specified moments, an information
establishing the identity of the transmitter.
The means of system identification should be approved by the appropriate national regulatory authority.
Annex A: provides additional information concerning radiated measurements.
Annex B: is normative and gives the requirements for equipment to be used for the measurement of
adjacent channel power.
Annex C: is normative and gives a graphic representation of subclause 4.1.2, referring to the
presentation of equipment for testing purpose.
Annex D: is informative and presents the technical characteristics to be fulfilled, when required by
the appropriate national regulatory authority, for the identification of stations type
approved for private mobile radio systems, that do not comply with other system protocols
(e.g. trunking protocols); it is the responsibility of the manufacturer to ensure that the
modulation that he has chosen for the identification, in accordance with the tables of this
annex fulfils the requirements corresponding to the channels where the equipment is
designed to operate, as specified in the main body of this standard. The tables of this
annex are expected to be updated regularly in order to reflect the progress accomplished
in the field of mobile data transmissions. It is envisaged that this annex could be normative
in the future when I-ETS 300 113 will be turned, when mature, into an ETS.

Annex E: is informative and provides guidance concerning the technical characteristics of the
modulation, coding and format.
Annex F: is normative, it applies to equipment to be operated in shared channels (for further details,
see Clause F.1); it also contains two methods of measurement used for the assessment
of receiver timing parameters. No other access protocol and occupation rules shall be
made mandatory for cases where this annex is applicable.
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 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 in subclause 4.3.
This standard will 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 of 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 4,
measurement methods, Clauses 8, 9 and 10, and conditions, Clauses 6 and 7.
This standard may also be used by monitoring services in particular for the identification of stations (see
Annex D).
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 measurement accepted by the various
authorities in order to grant type approval;
- if equipment available on the market is required to be checked it should be
tested in accordance with the methods specified in this standard.
This standard covers base stations, mobile stations and two categories of handportable stations. One
category is fitted with an antenna socket or connector. The other category has no external antenna socket,
but either:
- it is fitted with a permanent internal 50 Ω Radio Frequency (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 actually used during the type testing should be recorded by the accredited test
laboratory in the test report (see subclause 4.2.4).

1 Scope
This Interim European Telecommunication Standard (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 constant envelope angle modulation systems for use in the
land mobile service, using the available bandwidth, operating on radio frequencies between 30 MHz and
1000 MHz, with channel separations of 12,5 kHz, 20 kHz and 25 kHz intended for data transmissions. It
applies to non-speech and combined analogue speech/non-speech radio equipment for the transmission of
data.
It is also recognised that mobile data systems using high bit rates may have an occupied bandwidth which
is excessive for the existing channel separation. Equipment for such systems operating with modulation bit
rates higher than 2400 bits/s may be the subject of another standard, with different limits, although the
methods of measurement may be the same.
In this standard different requirements are given for the different radio frequency bands, channel
separations, etc., where appropriate.
In this standard, data transmission systems are defined as systems which transmit and/or receive data.
The equipment shall comprise of a transmitter and associated encoder and modulator and/or a receiver
and associated demodulator and decoder.
The types of equipment covered by this standard are as follows:
- Base Station (equipment fitted with an antenna socket, intended for use in a fixed
location);
- Mobile Station (equipment fitted with an antenna socket, normally used in a vehicle or
as a transportable);
- and those 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 following additional measurements shall be made with the
equipment antenna connected (and not through any connector):
- transmitter effective radiated power;
- transmitter radiated spurious emissions;
- receiver maximum usable sensitivity (data, field strength);
- receiver radiated spurious radiations.
Handportable equipment without an external or internal R.F. connector and without the possibility of having
a temporary internal 50 Ω RF connector is not covered by this standard.
In the case of combined full bandwidth analogue speech/full bandwidth non-speech equipment, if the
speech part of the equipment has already been type approved according to ETS 300 086 [2], only some
Page 12
I-ETS 300 113: January 1992
additional measurements have to be performed. They shall ensure that the equipment fulfils the
requirements of the following subclauses:
5.1.4 (Adjacent channel power);
5.1.5 (Spurious emission);
5.1.7 (Transmitter attack time);
5.1.8 (Transmitter release time);
5.1.9 (Transient behaviour of the transmitter);
5.2.1 (Maximum usable sensitivity (data, conducted));
5.2.2 (Maximum usable sensitivity (data, field strength));
5.2.3 (Bit error rate in normal operation);
5.2.4 (Co-channel rejection);
5.2.5 (Adjacent channel selectivity);
5.2.10 (Carrier sense delay); and,
5.2.11 (Receiver opening delay).
The measurement in subclause 8.6 (Spurious emissions) shall be performed when testing an add-on data
unit to an equipment previously type approved to ETS 300 086 [2]. In the case of equipment originally
combined for speech and data, the measurement does not need to be performed when the data-part is
operational while making the test corresponding to ETS 300 086 [2].
In the case where an equipment has already been type approved according to this standard, and is
resubmitted with an add-on device, using another type of modulation, only some additional measurements
have to be performed. They shall ensure that the equipment fulfils the requirements of the following
subclauses:
5.1.4 (Adjacent channel power);
5.1.5 (Spurious emission);
5.2.1 (Maximum usable sensitivity (data, conducted));
5.2.2 (Maximum usable sensitivity (data, field strength));
5.2.3 (Bit error rate in normal operation);
5.2.4 (Co-channel rejection);
5.2.5 (Adjacent channel selectivity);
5.2.11 (Receiver opening delay).
In the case where low bit rate data is transmitted together with speech, the speech part of the equipment
is tested according to ETS 300 086 [2], and it will also be checked that the low bit rate data does not
make the adjacent channel power and spurious emissions fall outside the appropriate limits.
