SIST EN 300 632 V1.2.1:2003

• Abstract:

  Extend the frequency band of the ETS 300 632 from 24.25 - 29.5 GHz to 24.25 - 31.8 GHz and modify equipment parameters if necessary. During this redrafting the opportunity will be taken to implement current TM4 practice and replace the ETS with an EN. For example, the section dealing with spurious emission, which currently defines limits, will be changed to reference CEPT Rec. 74-01. A section dealing with EMC will be added. Note. Currently the United Kingdom authorises the use of the frequency ranges from 31.0 to 31.3 GHz and 31.5 to 31.8 GHz for analogue security video systems using a Voluntary National Standard (VNS). The European Commission have authorised the use of the VNS but strongly recommended that the Radiocommunications Agency initiate work within TM4 to draft a European standard for 31 GHz analogue surveillance systems.

SIST EN 300 632 V1.2.1:2003 is the Slovenian adoption of ETSI EN 300 632 V1.2.1, a European standard for fixed radio link equipment that transmits analogue video signals. It specifies the minimum technical requirements for terrestrial analogue radio relay systems in the 24.25 GHz to 29.5 GHz and 31.0 GHz to 31.8 GHz bands, mainly for manufacturers, integrators, test labs, and buyers of point-to-point and video distribution links.

What does SIST EN 300 632 V1.2.1:2003 specify?

SIST EN 300 632 V1.2.1:2003 specifies the technical requirements for analogue fixed radio relay systems used for Point-to-Point (P-P) connections and video distribution Point-to-MultiPoint (P-MP) applications. It covers channel arrangements, interfaces, transmitter and receiver limits, system performance, and the environmental and EMC conditions the equipment is expected to meet.

The scope also makes clear that the standard is for analogue video links. Safety matters are outside the ETSI mandate, and the 31 GHz band is restricted here to analogue security video systems.

The document is organized into clauses 1 to 8, followed by one informative annex:

Annex	What it covers
Annex A	Bibliography

What are the key requirements of SIST EN 300 632 V1.2.1:2003?

Frequency bands and channel plan

Clause 4.1 aligns the 24.25 GHz to 29.5 GHz channel arrangements with CEPT Recommendation T/R 13-02 and ITU-R Recommendation F.748. For the 31.0 GHz to 31.8 GHz bands, the document applies a 28 MHz channel spacing basis.

In practice, this is what an operator or designer uses to choose the legal channel raster and to plan frequency assignments without conflicting with the band plan.

Environmental and EMC conditions

Clause 4.3 ties the equipment to ETS 300 019 environmental classes for weather protected and non-weather protected locations, and clause 4.4 requires operation under EN 301 489-1 and EN 301 489-4 EMC conditions.

In practice, this tells you which site conditions and immunity/emission requirements the equipment must be designed and tested against.

Interfaces, antenna-related items, and power supply

Clauses 4.6 and 5 set the interface references for antennas, waveguide flanges, XPD, power supply, and baseband connections. Where integral antennas are not used, IEC 60154 flange types are specified, and the video, audio, and IF interfaces point to ITU-T J.61, ITU-T J.21, and ITU-R F.403.

This matters because it fixes the mechanical and electrical interfaces a system has to match during integration and acceptance testing.

Baseband use

Clause 5 allows a video baseband bandwidth of up to 10 MHz and notes that subcarriers may carry CW, audio, wideband analogue, or digital signals.

That helps users decide whether the link can carry the intended service mix and what must be checked at baseband design stage.

Transmitter limits and spectrum control

Clause 6 sets transmitter output power at point C' to +5 dBm to +27 dBm, with tolerance depending on the site class. It also requires the transmitted spectrum to fit the applicable masks, with measurements based on 100 % colour bars for television, and keeps short-term RF tolerance below ±20 ppm.

In practice, this is the core conformance check for transmitter adjustment, RF testing, and spectrum measurements.

Spurious emissions and receiver performance

Clauses 6.4, 7.2, 7.3, and 7.4 require spurious emissions to follow CEPT/ERC Recommendation 74-01, set a receiver noise figure limit of 11 dB, and define receiver sensitivity thresholds tied to ITU-R picture quality grade 5.

This matters because it defines whether the link will coexist with other spectrum users and whether the receiver is sensitive enough for the expected video quality.

Interference sensitivity

Clause 8.2 covers co-channel, adjacent-channel, and CW spurious interference tests. It specifies how wanted and interfering signals are applied and the maximum permitted degradation in output signal quality.

In practice, these tests show how the receiver behaves in a crowded RF environment, which is important for coordination and field acceptance.

What terms does SIST EN 300 632 V1.2.1:2003 define?

• Carrier to Noise ratio (C/N) - The ratio used to describe how strong the wanted carrier is compared with noise, and the standard uses it to link RF performance with picture quality.
• Signal to Noise ratio (S/N) - The ratio of signal level to noise level in the video path, used in the performance tables.
• Intermediate Frequency (IF) - The internal radio frequency used between RF and baseband stages, especially for interface and interference testing.
• Point-to-Point (P-P) - A link between two fixed sites, which is one of the main intended applications of the standard.
• Point-to-MultiPoint (P-MP) - A distribution setup from one site to multiple receiving sites, used here for video distribution.
• Cross-Polar Discrimination (XPD) - The ability of an antenna or link to separate orthogonal polarizations, important for spectrum reuse and interference control.
• Continuous Wave (CW) - A steady unmodulated signal, used here as a test and pilot type in subcarriers.

Who uses SIST EN 300 632 V1.2.1:2003?

SIST EN 300 632 V1.2.1:2003 is used by equipment manufacturers, RF and system designers, test laboratories, operators, and procurement or quality teams for analogue microwave links. They use it to select channel spacing, define interfaces, verify transmitter and receiver parameters, plan EMC and environmental testing, and check whether a link is suitable for TV contribution, TV distribution, surveillance video, or radar signal remoting.

What changed in SIST EN 300 632 V1.2.1:2003 from the previous edition?

SIST EN 300 632 V1.2.1:2003 extends the earlier ETS 300 632 coverage from 24.25 GHz to 29.5 GHz up to 31.8 GHz. It also replaces specific antenna radiation pattern text with references to EN 300 833 and EN 301 215-4, changes spurious emission handling to reference CEPT/ERC Recommendation 74-01, and adds EMC requirements.

Which standards are used with SIST EN 300 632 V1.2.1:2003?

• CEPT Recommendation T/R 13-02 - Provides preferred channel arrangements for fixed services in the 22.0 GHz to 29.5 GHz range.
• ITU-R Recommendation F.748 - Gives radio-frequency arrangements for fixed service systems in the 25, 26, and 28 GHz bands.
• ETS 300 019 - Defines environmental classes and test severities for telecommunications equipment.
• EN 301 489-1 and EN 301 489-4 - Provide the EMC requirements for radio equipment and fixed radio links.
• IEC 60154 - Defines the waveguide flange types used when integral antennas are not used.
• ITU-T Recommendation J.61, ITU-T Recommendation J.21, and ITU-R Recommendation F.403 - Define video, audio, and IF interface characteristics.
• CEPT/ERC Recommendation 74-01 and ITU-R Recommendation F.1191-1 - Support the spurious emission framework.
• EN 300 833 and EN 301 215-4 - Cover antenna radiation patterns and XPD-related antenna requirements.
• ERC/DEC(00)09 and ERC Report 25 - Provide frequency-use context for the relevant bands.
• ITU Radio Regulations - Underpin the band availability and regulatory notes.

What does the SIST EN 300 632 V1.2.1:2003 document contain?

The document contains a system block diagram, channel plan guidance, spectrum masks, and measurement settings for RF spectrum analysis. It also gives tables for channel spacing, transmitter and receiver performance, C/N requirements, and interference tests. Figures 2a to 2c define the spectral masks for standard deviation, wide deviation, and 31 GHz operation, which are the main references for transmitter compliance testing. Annex A gives the bibliography used by the standard.

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.
