SIST EN 300 113-1 V1.4.1:2003 is the Slovenian adoption of ETSI EN 300 113-1 V1.4.1 for land mobile radio equipment. It specifies technical characteristics and measurement methods for equipment with an antenna connector that transmits data and/or speech using constant or non-constant envelope modulation, for use in professional mobile radio service.
What does SIST EN 300 113-1 V1.4.1:2003 specify?
SIST EN 300 113-1 V1.4.1:2003 sets the minimum performance requirements and the measurement methods for this class of radio equipment. The scope highlights the introduction of non-constant envelope modulation in ETS 300 113 to support coexistence with systems using 12.5 kHz, 20 kHz and 25 kHz channel spacing.
The standard is organized into 11 clauses plus six annexes. Clauses 1 to 3 cover scope, references, and definitions; clauses 4 to 7 cover general rules, test conditions, and test arrangements; clauses 8 to 10 give measurement methods for transmitter, receiver and duplex operation; clause 11 addresses measurement uncertainty.

|---|---|
| A | Radiated measurement arrangements and test sites |
| B | Requirements for measurement equipment used for adjacent channel power |
| C | Station identification characteristics and formats |
| D | Graphical selection of equipment and frequencies for testing |
| E | Information on modulation, coding and format |
| F | Bibliography |
What are the key requirements of SIST EN 300 113-1 V1.4.1:2003?
SIST EN 300 113-1 V1.4.1:2003 focuses on how equipment is chosen, tested, and judged. In practice, that means a manufacturer or test lab must select representative samples, use the defined test conditions, and apply the specified transmitter, receiver and duplex measurements.
General testing rules
Clause 4 covers equipment selection for testing, mechanical and electrical design, controls, transmitter shut-off facility, marking, interpretation of measurement results, and the use of bit streams or messages. This matters because the measured unit must represent the production model and the test setup must match the way the equipment actually operates.
Transmitter limits
Clause 5.1 lists transmitter parameters such as frequency error, carrier power, effective radiated power, adjacent channel power, spurious emissions, intermodulation attenuation, attack time, release time, and transient behaviour. For users, this is the part that controls spectral purity, output level and switching behaviour, all of which affect interference to nearby systems.
Receiver limits
Clause 5.2 sets receiver parameter limits for maximum usable sensitivity, average usable sensitivity, error behaviour at high input levels, co-channel rejection, adjacent channel selectivity, spurious response rejection, intermodulation response rejection, blocking or desensitization, and spurious radiations. This tells buyers and labs what the receiver must tolerate and how well it rejects unwanted signals.
Duplex operation
Clause 5.3 adds receiver limits for simultaneous transmission and reception, including receiver desensitization and spurious response rejection. This is important for duplex equipment because the transmitter can affect receiver performance during live operation.
Test conditions and setup
Clauses 6 and 7 define normal and extreme temperatures, power sources, signal arrangements, impedance, artificial antenna use, duplex filter arrangements, access points, and radiated-field test sites. These details matter because they make the measurements repeatable across laboratories and across different power and installation conditions.
Measurement methods
Clauses 8 to 10 give the measurement methods for transmitter parameters, receiver parameters, and duplex operation. Clause 8.10 is dedicated to transmitter transient behaviour, including time-domain measurements and adjacent channel transient power, while clause 9 covers the receiver tests and clause 10 covers duplex tests with a duplex filter or two antennas.
What terms does SIST EN 300 113-1 V1.4.1:2003 define?
The standard defines its own test language in clause 3. A few terms are especially useful when reading the measurement clauses.
- Constant envelope modulation - modulation where the envelope remains constant, which affects how transmitter power and adjacent channel tests are performed.
- Non-constant envelope modulation - modulation with a varying envelope, included here so the standard can cover newer data and speech systems.
- Adjacent channel power - unwanted power in channels next to the wanted channel, used to assess interference potential.
- Spurious emissions - emissions outside the wanted channel, measured to check spectral cleanliness.
- Maximum usable sensitivity - the weakest wanted signal a receiver can handle for data or messages under the defined test conditions.
- EUT - equipment under test, the device being measured.
- OFR - operating frequency range, used in Annex D when selecting samples and test frequencies.
Who uses SIST EN 300 113-1 V1.4.1:2003?
SIST EN 300 113-1 V1.4.1:2003 is used by manufacturers, accredited test laboratories, and conformity assessment bodies working on land mobile and professional mobile radio equipment. It is also relevant to national regulatory authorities and licensing administrations because the introduction notes that channel separation, maximum power, intermodulation class, and transmitter shut-off can be licensing conditions.
The document is aimed at equipment with an antenna connector used for data and/or speech transmission. Annex C is especially relevant when a regulatory authority requires station identification for professional mobile radio systems that do not use another system protocol.
What changed in SIST EN 300 113-1 V1.4.1:2003 from the previous edition?
This version is based on EN 300 113-1 version 1.3.1, which covered only constant envelope angle modulation equipment. SIST EN 300 113-1 V1.4.1:2003 extends the scope to include non-constant envelope modulation equipment as well.
Which standards are used with SIST EN 300 113-1 V1.4.1:2003?
The document points to EN 300 793 [3] for the graphical method used to select equipment and frequencies for testing. It also names EN 300 390 [2] for similar equipment with integral antennas, and EN 300 471-1 [11] for access protocols. The bibliography also cites EN 300 219, EN 300 296, EN 300 341 and EN 301 166 as related land mobile service standards.
What does the SIST EN 300 113-1 V1.4.1:2003 document contain?
The document contains detailed transmitter and receiver test methods, including conducted and radiated measurements, sensitivity and rejection tests, and duplex-operation checks. Annex A describes radiated test sites such as anechoic chambers and open area test sites, while Annex B specifies the measurement arrangements needed for adjacent channel power.
Annex C provides identification block formats, bit rates, synchronization, country/regional codes, and field combinations for station identification. Annex D gives graphs that help choose how many samples and which frequencies to test, especially when operating frequency range and alignment range differ. Annex E adds guidance on modulation, coding and format.

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 upon EN 300 113-1 (version 1.3.1) [10]. EN 300 113-1 (version 1.3.1) [10] covered only constant envelope angle modulation equipment. The present document covers both constant envelope angle modulation and non-constant envelope modulation equipment as described in the scope. This is a general standard which may be overridden or complemented by specific standards addressing specific applications. It applies to equipment designed to operate within the professional mobile radio service and to the associated frequency planning. Equipment similar to that covered by the present document, but using constant envelope modulation only (at the time of publication of present document) and having an integral antenna is covered by EN 300 390 [2] (for details, see the scope of the present document as well as the scope of EN 300 390 [2]).

ETSI ETSI EN 300 113-1 V1.4.1 (2002-02) 9 Access protocols for equipment covered by the present document are the subject of other ETSI standards such as EN 300 471-1 [11]. Channel separations, 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 relating to the issue of a licence by the appropriate administration. Annex A: is normative and provides additional information concerning radiated measurements. Annex B: is normative and gives the requirements for equipment to be used for the measurements of adjacent channel power. Annex C: is normative and presents the technical characteristics to be fulfilled, when required by the appropriate national regulatory authority, for the identification of stations for professional 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 equipm
