SIST EN 302 296 V1.1.1:2005 is the Slovenian adoption of ETSI EN 302 296 V1.1.1 for transmitting equipment used in the terrestrial digital television broadcast service (DVB-T). It specifies radio spectrum and unwanted-emissions requirements under article 3.2 of the R&TTE Directive, so manufacturers, test labs, and regulators can check how DVB-T transmitters use spectrum and limit interference.
What does SIST EN 302 296 V1.1.1:2005 specify?
SIST EN 302 296 V1.1.1:2005 applies to transmitting equipment for terrestrial digital television broadcasting, including equipment with 7 MHz and 8 MHz RF channel bandwidths operating in the CEPT frequency bands used in television Bands III, IV and V. The standard focuses on the spectrum-use requirement in article 3.2 of the R&TTE Directive, and it sits inside the ETSI modular framework for radio and telecommunications equipment.
The document is organized into four clauses plus three annexes. Clause 1 gives the scope, Clause 2 lists references, Clause 3 defines terms, symbols and abbreviations, and Clause 4 contains the technical requirements. Annex A gives the general measuring arrangements, Annex B lists bibliography items, and Annex C provides the title in official languages.
| Annex | What it covers |
|---|---|
| Annex A | Normative measuring arrangements for antenna port and enclosure port tests |
| Annex B | Informative bibliography and background references |
| Annex C | Informative EN title in official languages |
What are the key requirements of SIST EN 302 296 V1.1.1:2005?
SIST EN 302 296 V1.1.1:2005 is mainly about unwanted emissions from DVB-T transmitters and how to measure them. The practical outcome is that the transmitter must be set up, driven and reported in a way that shows both spectrum efficiency and radiated-emission control.
Environmental profile and test conditions
Clause 4.1 requires the supplier to declare the environmental profile for operation. The equipment must meet the standard whenever it operates within that declared range. In practice, the test report should say where the transmitter is expected to run, because the measurements are only meaningful if the declared operating environment matches real use.
Antenna port measurements
Clause 4.2 covers antenna port measurements for spurious emissions and out-of-band emissions. For both tests, the equipment is operated at the lowest, highest and mid-way operating frequencies, and the manufacturer must keep the transmitter at full rated output power during the test. That matters because the result has to represent worst-case transmitter behavior, not a reduced-power condition.
For spurious emissions, Clause 4.2.1 defines the unwanted energy outside the necessary bandwidth but outside the channel-adjacent region defined for this standard. The limits vary by frequency region and by transmitter power, so the test lab has to select the correct limit case for the equipment under test. If the transmitter has no internal bandpass output filter, the manufacturer must state the filter characteristics needed to meet the limits and include that information in the test report.
For out-of-band emissions, Clause 4.2.2 treats energy immediately outside the necessary bandwidth, but still within the channel-adjacent region defined by the document. The standard distinguishes non-critical and critical cases, because adjacent services can change how much attenuation is needed close to the channel edges. That means the engineer must decide whether the transmitter is intended for ordinary channels or for tighter sharing conditions near other services.
Enclosure port measurements
Clause 4.3 covers cabinet radiation, which is radiation from the enclosure rather than from the antenna path. The test method follows EN 55022, unless the physical size of the equipment requires EN 55011 instead. The measurement setup must use a normal operating mode that produces the largest emission in the band under test, with cables moved as needed to maximize the detected radiation.
Clause 4.3 also requires the RF input/output ports to be correctly terminated, the configuration and operating mode to be recorded, and the equipment to be tested at the rated supply voltage within the declared environmental range. In practice, this is the part that shows whether the transmitter enclosure itself creates unwanted radiated energy that could affect nearby equipment.
Measurement uncertainty
Clause 4.4 says measurement uncertainty should be calculated and reduced where possible, and that the uncertainty should be applied to the limit in line with TR 100 028. For users of the standard, this means a result is not just a single number on a receiver display - the lab must also understand the confidence range around that number.
General measuring arrangements
Annex A supports the test clauses with the measurement setups for spurious emissions, out-of-band emissions, and radiated emissions. It also fixes the modulation settings used for the transmitter input signal during testing, using the DVB-T framing and modulation defined in EN 300 744 with specific operating parameters. This matters because the unwanted-emission result depends on how the transmitter is driven.
What terms does SIST EN 302 296 V1.1.1:2005 define?
- Antenna port - the connection point intended for coaxial cable to an antenna in normal operation.
- Broadcasting service - a radiocommunication service intended for direct reception by the general public.
- Cabinet radiation - radiation from the enclosure of the equipment, excluding connected antennas or cables.
- DVB-T - Digital Video Broadcasting - Terrestrial, the terrestrial digital television broadcasting system covered by the standard.
- EUT - Equipment Under Test, the transmitter or transmitter assembly being measured.
- Out-of-band emissions - unwanted emissions just outside the necessary bandwidth, produced by modulation and not counted as spurious emissions.
- Spurious emissions - unwanted emissions outside the necessary bandwidth that can be reduced without affecting the information being transmitted.
Who uses SIST EN 302 296 V1.1.1:2005?
This standard is used by manufacturers of DVB-T transmitting equipment, especially when they need to design output filtering, select operating modes, and prepare technical files. Test laboratories use it for spectrum measurements, radiated-emission checks, and test reporting. Quality managers and compliance teams use it to set acceptance criteria for transmitter builds, while broadcasters and network operators use it when procuring or accepting equipment for terrestrial digital TV networks. Regulatory and conformity-assessment teams use it to document that a transmitter has been evaluated against the article 3.2 spectrum-use requirement.
Which standards are used with SIST EN 302 296 V1.1.1:2005?
| Reference | What it contributes |
|---|---|
| EN 301 489-14 | EMC conditions for analogue and digital terrestrial TV broadcasting service transmitters |
| EN 300 744 | DVB-T framing, channel coding and modulation settings used for the test signal |
| EN 55022 | Radiated-emissions measurement method used for cabinet radiation when size allows |
| EN 55011 | Alternative radiated-emissions method when physical size is a restriction |
| IEC 60489-1 | General measurement definitions and standard conditions of measurement |
| TR 100 028 | Guidance on measurement uncertainties and how to apply them |
| Directive 1999/5/EC | The R&TTE legal framework under which the harmonized standard is intended to apply |
What does the SIST EN 302 296 V1.1.1:2005 document contain?
The document contains limit tables and figures for unwanted emissions, including separate treatments for spurious emissions, out-of-band emissions, and cabinet radiation. It also contains step-by-step test procedures, initial conditions, test frequencies, and notes on filter arrangements and test configurations. Annex A adds the measurement setups and the recommended test bandwidths, while the figures show how the limits vary with transmitter power and frequency region. For anyone planning verification testing, the document is mainly a measurement and reporting guide for DVB-T transmitter compliance work.

The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [2].
For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present
document essential requirements in these areas have to be adopted by the Commission. If such essential requirements
are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to
be specified by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.
For article 3.1b the diagram shows EN 301 489, the multi-part product EMC standard for radio used under the EMC
Directive [3].
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [4] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive [2] is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive [2] may be covered in a set of standards.
The modularity principle has been taken because:
• it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur in an equipment;
• it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions
without requiring alteration of standards that are already published;
• it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity
assessment.

1 Scope
The present document applies to transmitting equipment for the terrestrial digital television broadcasting service.
The types of equipment covered by the present document are as follows:
• Transmitting equipment for digital television broadcasting service, with 7 MHz and 8 MHz RF channel
bandwidths, operating in the CEPT frequency bands. These frequencies are currently within the television
Bands III, IV and V.
The present document is intended to cover the provisions of article 3.2 of Directive 1999/5/EC [2] (R&TTE Directive),
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the R&TTE Directive [2] may apply to equipment within the scope of the present
document.
