SIST EN 302 018-1 V1.1.1:2003 is the Slovenian adoption of ETSI EN 302 018-1 V1.1.1, published by SIST. It covers transmitting equipment for the Frequency Modulated (FM) sound broadcasting service and sets technical characteristics plus test methods for FM transmitters operating from 68 MHz to 108 MHz. The document is aimed at manufacturers, test laboratories, and conformity assessment teams that need a common way to specify and verify FM broadcast transmitter performance.

What does SIST EN 302 018-1 V1.1.1:2003 specify?

SIST EN 302 018-1 V1.1.1:2003 specifies the technical characteristics and measurement methods for FM sound broadcasting transmitting equipment, including monophonic and stereophonic operation in the 68 MHz to 108 MHz band. The document organizes these requirements into clauses for definitions, technical requirements, and compliance testing, with normative annexes for the measuring arrangements.

What are the key requirements of SIST EN 302 018-1 V1.1.1:2003?

SIST EN 302 018-1 V1.1.1:2003 focuses on transmitter performance that matters in service: output power, frequency stability, audio-to-RF conversion, unwanted emissions, and radiated cabinet emissions. In practice, it tells you what to measure, under which setup, and how to compare the result with the limits in Clause 4.

Transmitter configuration and output behavior

Clause 4.1 says that if a transmitter does not include a stereo encoder and is intended for stereo operation, a suitable test encoder shall be used. That matters because the test setup must match the intended operating mode before any measurement is meaningful.

Clause 4.2.1 covers rated output power, and Clause 4.2.2 covers frequency stability. The first checks that the carrier output matches the declared rating, while the second checks long-term frequency drift. For a buyer or lab, this is the basic evidence that the transmitter stays on channel and delivers the expected RF level.

Modulation performance

Clauses 4.2.3 to 4.2.8 cover transmitter muting during frequency shift, deviation sensitivity stability, residual AM, synchronous AM, modulator performance, and FM signal-to-noise ratio (SNR). These requirements address how cleanly the transmitter turns audio into FM and how well it suppresses unwanted amplitude effects and noise. In practice, they show whether the unit can preserve broadcast quality without excessive distortion or noise.

Unwanted emissions and cabinet radiation

Clause 4.2.9 covers spurious emissions and Clause 4.2.10 covers out-of-band emissions. These are the emissions outside the wanted channel that can interfere with other services, so they are central for spectrum compliance.

Clause 4.3.1 covers cabinet radiation from the enclosure port. This matters because a transmitter can radiate unwanted energy from its housing and cabling even when the antenna output is correct.

Compliance testing

Clause 5 describes the test approach for compliance with the technical requirements. It includes measurement uncertainty handling, then a suite of essential radio tests for each requirement. For a test house, this clause is the practical checklist for setting up the equipment under test (EUT), applying the test signal, and recording the result.

What terms does SIST EN 302 018-1 V1.1.1:2003 define?

• Carrier power - the average power delivered to the antenna transmission line during one cycle with no modulation.
• Multiplex (MPX) signal - the combined signal that carries the pilot tone and any supplementary signal used to frequency modulate the VHF FM transmitter.
• Pilot tone - the 19 kHz tone used to recover the stereo subcarrier in a stereo receiver.
• Radio Data System (RDS) - a signal carrying programme and network information on a 57 kHz subcarrier.
• Spurious emissions - emissions outside the necessary bandwidth that can be reduced without affecting information transmission.
• Out-of-band emissions - emissions immediately outside the necessary bandwidth that arise from the modulation process.
• Equipment Under Test (EUT) - the transmitter being measured in the compliance test setup.
• Signal to Noise (S/N) - the ratio used to express noise performance in the FM output chain.

Who uses SIST EN 302 018-1 V1.1.1:2003?

This standard is used by FM transmitter manufacturers, RF design engineers, broadcast equipment test laboratories, and quality or compliance teams. It is also useful for buyers and operators specifying new transmitters, because it defines the measurements that show whether equipment meets declared RF and modulation performance.

Which standards are used with SIST EN 302 018-1 V1.1.1:2003?

• Directive 1999/5/EC (R&TTE Directive) - the regulatory framework referenced by the standard’s scope.
• ITU-R Recommendation BS.412 - used for planning standards and measurement uncertainty treatment.
• EN 60244-13 - supplies the methods used for residual AM and synchronous AM measurements.
• EN 55011 - provides guidance for radiated measurement practice when cabinet radiation testing is done at a manufacturing facility.
• ETSI EN 302 018-2 - the companion part identified in the foreword.
• ETSI EN 301 489-11 - the associated EMC standard for terrestrial sound broadcasting service transmitters.
• ITU-R Recommendation BS.468-4 - used for weighted FM noise measurement in the SNR test.
• ITU-R Recommendation SM.329 - defines reference bandwidth for unwanted emission measurements.
• IEC 60489-1 - provides general measurement definitions and standard conditions.
• EN 50067 - defines the RDS signal referred to in the terms section.

What does the SIST EN 302 018-1 V1.1.1:2003 document contain?

The document contains clause-by-clause definitions, technical limits, and test methods for FM sound broadcasting transmitters. It includes a set of essential radio test suites in Clause 5, with initial conditions, procedures, and test requirements for each item.

Annex A provides the practical test setup: the measurement chain, recommended frequency range for unwanted emissions, reference bandwidths, the test modulating signal, radiated measurement guidance, and test load characteristics. The figures and tables in Clauses 4 and 5 provide the masks, limits, and test arrangements used for design verification, type testing, and compliance assessment.
