SIST EN 300 632 V1.2.2:2003 is the Slovenian adoption of ETSI EN 300 632 V1.2.2, a European telecommunications standard for fixed radio link equipment carrying analogue video signals. It specifies the minimum technical requirements for terrestrial analogue radio relay systems in the 24,25 GHz to 29,50 GHz and 31,0 GHz to 31,8 GHz bands, for manufacturers, integrators, test laboratories, operators and regulators.

What does SIST EN 300 632 V1.2.2:2003 specify?

SIST EN 300 632 V1.2.2:2003 specifies minimum technical requirements for analogue fixed radio relay systems used for point-to-point and point-to-multipoint video distribution. It also sets the structure of the document through clauses on scope, references, symbols, general characteristics, baseband, transmitter, receiver and system performance, plus one informative annex.

The scope includes contribution TV, distribution TV, surveillance video and radar signals remoting. The 31 GHz band is restricted in this standard to analogue security video systems, and safety aspects are outside its scope.

What are the key requirements of SIST EN 300 632 V1.2.2:2003?

SIST EN 300 632 V1.2.2:2003 ties together spectrum planning, interfaces, environmental classes, transmitter and receiver limits, and interference tests. In practice, it tells a supplier what frequency plan, external interfaces and radio performance the equipment must meet before it is considered compliant.

Frequency bands, channel arrangements and compatibility

Clause 4.1 aligns the channel plan in the 24,25 GHz to 29,50 GHz range with CEPT and ITU-R recommendations, and it extends coverage to the 31 GHz bands when the channel arrangement uses 28 MHz spacing. Clause 4.2 states that conforming equipment is not guaranteed to interwork across the radio interface with another manufacturer’s equipment, so buyers should not assume plug-and-play compatibility between brands.

Environmental and EMC conditions

Clause 4.3 requires the equipment to meet ETS 300 019 environmental classes for weather protected and non-weather protected locations. Clause 4.4 requires operation under EN 301 489-1 and EN 301 489-4 conditions, which means EMC needs to be checked as part of the product design and test plan, not left to site acceptance.

Antenna, feeder and power interfaces

Clause 4.6 points to EN 300 833 for antenna radiation patterns and to IEC 60154 for waveguide flange types. Clause 4.7 refers to the power supply interface standards, so the radio and its ancillary equipment have to be matched not only on RF performance but also on mechanical and power-entry interfaces.

Baseband interfaces

Clause 5 allows a video baseband bandwidth of up to 10 MHz and notes that subcarriers may carry continuous wave, low frequency analogue, wideband analogue or digital signals. The video interface is linked to ITU-T J.61, the audio interface to ITU-T J.21, and the IF interface to ITU-R F.403, so interface checks must follow the relevant companion recommendation.

Transmitter limits and spectrum control

Clause 6.1 sets the transmitter output power range at point C'. Clause 6.2 then limits output power tolerance differently for weather protected and non-weather protected locations, while clauses 6.3 to 6.5 control radiated spectrum, spurious emissions and radio frequency tolerance. For the user, this means the radio must be set up so its occupied spectrum stays inside the allowed masks when tested with the specified signals.

Receiver performance and interference tests

Clause 7 sets receiver input level range, spurious emission limits, noise figure and sensitivity. Clause 7.4 ties sensitivity to ITU-R picture quality grade 5, and clause 8 adds interference sensitivity tests for co-channel, adjacent-channel and CW spurious interference, so acceptance testing has to include both wanted-signal performance and robustness against interferers.

What terms does SIST EN 300 632 V1.2.2:2003 define?

• C/N (Carrier to Noise ratio) - The ratio used to express how much wanted carrier power stands above noise, and it is central to the performance and interference checks.
• S/N (Signal to Noise ratio) - The ratio of useful signal to noise at the output, used here to relate picture quality to receiver performance.
• IF (Intermediate Frequency) - A frequency stage used inside the radio system and in the IF interface between equipment.
• P-P (Point-to-Point) - A link between two fixed stations, used for direct radio relay connections.
• P-MP (Point-to-MultiPoint) - A distribution arrangement where one station serves multiple remote points.
• CW (Continuous Wave) - A single-frequency test or pilot signal used as a subcarrier type and in interference testing.
• XPD (Cross-Polar Discrimination) - A measure of isolation between orthogonal polarizations, relevant to antenna performance.

Who uses SIST EN 300 632 V1.2.2:2003?

SIST EN 300 632 V1.2.2:2003 is used by makers of fixed radio link equipment, especially for analogue video transmission in microwave bands. It is also used by system designers, RF test laboratories, network operators, and regulators who need to specify, verify or purchase links for TV contribution, TV distribution, surveillance video and radar signal remoting.

What changed in SIST EN 300 632 V1.2.2:2003 from the previous edition?

SIST EN 300 632 V1.2.2:2003 replaces the earlier ETS 300 632 V1.2.1 version. The foreword says this version extends the standard to cover the 31,0 GHz to 31,8 GHz bands and replaces the specific antenna radiation patterns with references to EN 300 833 and EN 301 215-4. The revision was produced to correct an editorial error.

1 Scope The present document covers the minimum technical requirements for terrestrial analogue radio relay systems operating in bands in the frequency range 24,25 GHz to 29,5 GHz and 31,0 GHz to 31,8 GHz.
Such systems are intended to be used for Point-to-Point (P-P) connections and video distribution (Point-to-Multipoint (P-MP)). Typical applications include: a) TV of contribution quality; b) TV of distribution quality; c) TV of surveillance quality; d) Radar signals remoting. Use of the 31 GHz band is restricted to analogue security video systems in the present document. Safety aspects are outside the mandate of ETSI and they will not be considered in the present document. The requirements and limits given in the present document are relevant to all environmental conditions for the chosen climatic class. The minimum performance parameters for digital radio relay equipment operating in the range 24,5 GHz to 29,5 GHz are set out in EN 300 431 [12] while those for systems operating in the range 31,0 GHz to 31,3 GHz and 31,5 GHz to 31,8 GHz are given in EN 300 197 [15]. The 31,0 GHz to 31,3 GHz band is available in some countries and included in CEPT Report 25 [17].
All emissions are prohibited in the band 31,3 GHz to 31,5 GHz (see footnote S5.340 in ITU Radio Regulations [20]). Therefore this band is not available for FS systems. The levels of unwanted emissions from FS systems falling into the band 31,3 GHz to 31,5 GHz are, at the time of writing, being discussed under Agenda item 1.8.2 of WRC 03. It should be noted that the band 31,5 GHz to 31,8 GHz, available for FS in some Countries under the provision of footnote S5.546 of the ITU Radio Regulations [20], is also allocated to passive services, including the Earth Exploration Satellite Service (EESS passive). 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.
