SIST EN 302 017-1 V1.1.1:2006 is the Slovenian adoption of ETSI EN 302 017-1, issued by SIST. It specifies technical characteristics and test methods for Double Side Band transmitting equipment used in the AM sound broadcasting service in the LF, MF and HF bands. Engineers, test laboratories, and buyers can use it to check transmitter output power, frequency stability, unwanted emissions, and cabinet radiation in a consistent way.

What does SIST EN 302 017-1 V1.1.1:2006 specify?

SIST EN 302 017-1 V1.1.1:2006 applies to Double Side Band transmitting equipment for amplitude-modulated radio broadcast service. In practice, it is the part of the AM broadcast transmitter standard that tells users what to measure and how to measure it.

The document is organized into:

• Clause 1 - Scope
• Clause 2 - References
• Clause 3 - Definitions, symbols and abbreviations
• Clause 4 - Technical requirements specifications
• Annex A - General measuring arrangements
• Annex B - Bibliography

Annexes A and B are informative. Annex A gives the practical test setups and signal conditions used by the methods in Clause 4, while Annex B lists background documents.

What are the key requirements of SIST EN 302 017-1 V1.1.1:2006?

SIST EN 302 017-1 V1.1.1:2006 focuses on a small set of transmitter characteristics that matter for broadcast quality and spectrum control. The main checks are output power, long-term frequency drift, spurious emissions, muting during retuning, out-of-band emissions, and cabinet radiation.

Environmental profile

Clause 4.1 requires the supplier to declare the environmental profile, and the equipment has to meet the technical requirements while operating within that declared range. For users, this means the operating conditions must be stated before testing or acceptance, so test results match the real deployment environment.

Rated output power

Clause 4.2.1 defines rated output power as the carrier power delivered at the antenna port under the manufacturer’s stated operating conditions. The measurement is taken at the lowest, highest, and mid-range operating frequencies. The result has to stay within ±1.0 dB of the rated value, so the transmitter can be checked for consistent delivered power across its tuning range.

Frequency drift

Clause 4.2.2 covers uncontrolled continuous and irreversible frequency variation. The transmitter frequency has to remain within ±10 Hz for a period of not less than ninety days. In practice, this is a stability requirement that matters for channel placement and long-term broadcast reliability.

Spurious emissions and transmitter muting

Clause 4.2.3 defines spurious emissions and limits them over the range 9 kHz to 1 GHz. Clause 4.2.4 says transmitter muting during frequency shift has to meet the same limit approach as spurious emissions. For operators and labs, this means retuning must not create unwanted signals that could interfere with other services.

Out-of-band emissions

Clause 4.2.5 covers emissions immediately outside the necessary bandwidth that come from the modulation process. The measurement uses a standardized coloured-noise test signal, repeated at least five times and averaged. This matters because AM transmitters must keep spectral energy close to the wanted channel shape, not just suppress far-away spurs.

Cabinet radiation

Clause 4.3.1 covers radiated emissions from the enclosure, separate from the antenna port. The limits apply from 30 MHz to 1 GHz, with measurements normally made at 10 m where feasible. This is important for installation and EMC checking because the transmitter enclosure itself can radiate into the surrounding environment.

Measurement uncertainty

Clause 4.4 says measurement uncertainty should be calculated and minimized, and that the uncertainty should be applied to the limit in line with TR 100 028. In practice, this means compliance decisions should take measurement accuracy into account, not just a single instrument reading.

What terms does SIST EN 302 017-1 V1.1.1:2006 define?

• Antenna port - The physical port intended to connect to an antenna by coaxial cable during normal operation.
• Cabinet radiation - Radiation from the enclosure of the equipment, excluding radiation from connected antennas or cables.
• Carrier power - The average power delivered to the antenna transmission line during one cycle with no modulation.
• Environmental profile - The range of environmental conditions in which the equipment is required to comply with the standard.
• Necessary bandwidth - The width of spectrum needed to transmit the information with the required rate and quality.
• Spurious emissions - Unwanted emissions outside the necessary bandwidth that can be reduced without affecting the wanted transmission.
• Out-of-band emissions - Emissions just outside the necessary bandwidth that result from modulation, but are not spurious emissions.

Who uses SIST EN 302 017-1 V1.1.1:2006?

SIST EN 302 017-1 V1.1.1:2006 is used by transmitter manufacturers, EMC and radio test laboratories, broadcast network operators, and compliance teams working on AM sound broadcasting equipment. It is also useful for quality managers and buyers who need to specify or verify broadcast transmitters for LF, MF, or HF service.

Typical tasks include design verification, type testing, factory acceptance testing, and documenting operating conditions and emissions performance. It is especially relevant when a team needs to confirm that a transmitter can deliver the expected carrier power, stay frequency-stable, and remain within unwanted-emission limits.

Which standards are used with SIST EN 302 017-1 V1.1.1:2006?

The document names several standards and reports that support its measurements and related compliance work:

• ETSI EN 302 017-2 - the companion part for the harmonized EN under Article 3.2 of the R&TTE Directive.
• ETSI EN 301 489-11 - the EMC standard that gives specific conditions for terrestrial sound broadcasting service transmitters.
• CENELEC EN 55011 - used when cabinet-radiation testing has to follow a recognized radiated-emissions method.
• ETSI TR 100 028 - provides the approach for measurement uncertainty.
• ITU-R Recommendation SM.329-10 - gives the basis for reference bandwidth used in spurious-emission work.
• IEC 60489-1 - gives general measurement definitions and standard conditions, and is referenced for typical radiated test sites.

What does the SIST EN 302 017-1 V1.1.1:2006 document contain?

Clause 4 contains the main technical methods and limits for rated output power, frequency drift, spurious emissions, transmitter muting during frequency shift, out-of-band emissions, cabinet radiation, and measurement uncertainty. Each method includes initial conditions, a test procedure, and the limit or acceptance criterion.

Annex A gives the practical measuring arrangements for antenna-port and radiated tests. It also describes the test frequency range, the standardized coloured-noise modulation signal, the reference bandwidths used for unwanted emissions, and the test load characteristics.

The figures and tables provide the limit curves and setup details that the procedures refer to, including the emission-limit plots and the test arrangements for transmitter measurements. For users, these parts are what turn the written requirements into repeatable lab tests.
