SIST EN 300 720-2:2001 is the Slovene adoption of ETSI EN 300 720-2, a harmonized European Standard for Ultra-High Frequency (UHF) on-board communications systems and equipment. It supports Article 3.2 of the R&TTE Directive by specifying the spectrum-related technical requirements and the tests used to check them. Manufacturers, suppliers, test laboratories and conformity assessors use it to verify transmitter and receiver performance for this equipment type.

What does SIST EN 300 720-2:2001 specify?

SIST EN 300 720-2:2001 specifies the harmonized requirements for UHF on-board communications systems and equipment that use class of emission G3E on single-frequency or two-frequency simplex channels. It is the part of the series that turns the technical material of EN 300 720-1 into an Article 3.2 conformity standard.

The scope is limited to the channel arrangements named in the document and to spectrum use, not to unrelated safety or general EMC topics. Clause 1 states the application area, Clause 2 lists the referenced documents, Clause 3 gives definitions and abbreviations, Clauses 4 and 5 set the technical requirements and test methods, and Annex A provides the EN Requirements Table (EN-RT).

What are the key requirements of SIST EN 300 720-2:2001?

Operating conditions

SIST EN 300 720-2:2001 applies under the equipment’s environmental profile, which is determined by the environmental class of the equipment. In practice, the equipment has to meet the standard not just in ideal laboratory conditions but throughout the declared operating environment.

Transmitter requirements

Clause 4 requires conformance for transmitter frequency error, carrier power, frequency deviation, adjacent channel power, transient frequency behavior, and spurious emissions. Each requirement uses the definitions and limits from EN 300 720-1, so the reader has to check the transmitter against the companion part rather than derive new limits from this document alone.

That matters in practice because these checks control whether the transmitter stays on frequency, stays within its intended power and deviation, and avoids unwanted emissions that could interfere with other users of the band.

Receiver requirements

Clause 4 also sets requirements for receiver maximum usable sensitivity, co-channel rejection, adjacent channel selectivity, spurious response rejection, intermodulation response, blocking or desensitization, and receiver spurious emissions. For most receiver items, the clause points to EN 300 720-1 for the definition, the limit, and the related test.

In practice, this is the part that shows whether a receiver can still work in a crowded radio environment. A buyer or engineer uses these limits to judge how well the equipment will handle wanted signals, nearby transmitters, and strong interfering signals.

Test conditions and uncertainty

Clause 5 says the test conditions, power supply arrangements and ambient temperatures come from EN 300 720-1. It also requires the test report to include measurement uncertainty and links that uncertainty to ETSI ETR 028.

This matters because compliance is decided against the measured value together with the uncertainty, so the test report has to show traceable and comparable results. Clause 5 also gives separate transmitter and receiver test suites that mirror the requirements in Clause 4.

EN-RT summary

Annex A contains the EN Requirements Table (EN-RT), which lists all requirements and marks them as mandatory. For conformity assessment, this gives a compact checklist that can be completed for a specific item of equipment.

What terms does SIST EN 300 720-2:2001 define?

• Environmental profile - the range of environmental conditions in which the equipment must still comply with the standard.
• Supplier - the entity responsible for placing the equipment on the market under the R&TTE Directive.
• UHF - Ultra-High Frequency, the radio-frequency region covered by the equipment in this standard.
• G3E - the class of emission used for the on-board communications systems and equipment in scope.
• EMC - Electromagnetic compatibility, the ability of equipment to operate without causing or suffering unacceptable interference.
• EN-RT - EN Requirements Table, the annex that summarizes the requirements and their mandatory status.

Who uses SIST EN 300 720-2:2001?

Manufacturers and suppliers of UHF on-board communications systems and equipment use SIST EN 300 720-2:2001 during design and product verification. Test laboratories use it to run the transmitter and receiver conformance tests named in Clause 5.

Quality managers, regulatory specialists and conformity assessment bodies use it to prepare and review evidence for Article 3.2 compliance. It is also relevant to maritime and other onboard radio-equipment projects where the equipment must fit the specified channels and spectrum-use conditions.

What does the SIST EN 300 720-2:2001 document contain?

SIST EN 300 720-2:2001 contains the scope for UHF on-board communications equipment, a reference list, definitions and abbreviations, the technical conformity requirements, and the test provisions used to verify them. Clause 4 is organized as paired transmitter and receiver requirements, each linked to EN 300 720-1 for the exact definition and limit.

Clause 5 gives the test conditions, the measurement-uncertainty approach, and the essential radio test suites for transmitter and receiver performance. Annex A provides the EN-RT proforma, which is used as a conformity checklist and as the basis for static assessment of compliance.
