SIST EN 301 025-2:2001 is the Slovenian adoption of ETSI EN 301 025-2 V1.1.1, a harmonized European standard for VHF radiotelephone equipment for general communications and associated equipment for Class D Digital Selective Calling (DSC). It specifies the radio-spectrum conformance requirements and test methods needed under Article 3.2 of the R&TTE Directive for equipment operating in the 156 MHz to 174 MHz Maritime Mobile Service band. It is written for manufacturers, suppliers, test labs and conformity assessors that need a clear basis for demonstrating that the equipment uses spectrum properly and avoids harmful interference.

What does SIST EN 301 025-2:2001 specify?

SIST EN 301 025-2:2001 sets the harmonized requirements for VHF radiotelephone equipment and associated Class D DSC equipment under Article 3.2 of Directive 1999/5/EC. In practice, it tells you what performance must be checked and how those checks are linked to the measurement methods in Part 1.

The document is organized into scope, references, definitions and abbreviations, technical requirement specifications, test provisions, and a normative annex with an EN Requirements Table.

What are the key requirements of SIST EN 301 025-2:2001?

SIST EN 301 025-2:2001 requires compliance with the stated limits under the relevant environmental profile for the equipment. That matters because the equipment has to meet the radio requirements in the conditions where it will actually be used.

Transmitter performance

The standard covers transmitter frequency error, adjacent channel power, conducted spurious emissions conveyed to the antenna, cabinet radiation and other conducted spurious emissions, transient frequency behaviour, carrier power, and frequency deviation. These checks matter because they control channel accuracy, unwanted emissions and stability during keying and modulation.

For each transmitter item, Clause 4 gives the requirement and Clause 5 points to the matching test method. The test result is then compared with the limit from Part 1, so manufacturers need both documents together when designing and validating the transmitter.

DSC signaling performance

The standard also covers DSC frequency error for the demodulated DSC signal, DSC modulation index, and DSC modulation rate. These requirements matter because Class D DSC signaling must be decoded reliably in maritime use, especially for distress, urgency, safety and routine calling.

Receiver performance

Receiver requirements include maximum usable sensitivity, co-channel rejection, adjacent channel selectivity, spurious response rejection, intermodulation response, blocking or desensitization, spurious emissions at the antenna, and cabinet radiated spurious emissions. The same set of checks is repeated for the DSC receiver, including maximum usable sensitivity, co-channel rejection, and spurious response and blocking immunity.

In practice, these receiver tests show whether the equipment can hear wanted signals while resisting interference from other transmitters nearby, on adjacent channels, or from strong unwanted signals.

Test conditions and measurement uncertainty

Clause 5 ties the tests to the conditions, power supply and ambient temperatures given in Part 1. It also requires the measurement uncertainty for each parameter to be stated in the test report and kept within the limits linked to the measurement uncertainty guidance in ETR 028.

That matters for test houses and buyers because the compliance decision is based on the measured value together with its uncertainty, not just on a raw reading.

EN Requirements Table

Annex A summarizes all EN-R requirements in one table and marks them as mandatory. That makes it useful for static conformity assessment and for checking which items must be implemented.

What terms does SIST EN 301 025-2:2001 define?

• Environmental profile - the range of operating environmental conditions within which the equipment must comply.
• Supplier - the entity responsible for placing the equipment on the market under the R&TTE Directive.
• Class D - equipment intended to provide minimum VHF DSC facilities for distress, urgency, safety and routine calling and reception.
• carrier frequency - the frequency to which the transmitter or receiver is tuned.
• frequency deviation - the difference between the instantaneous modulated RF signal frequency and the carrier frequency.
• G3E - phase-modulation used for speech, with frequency modulation and 6 dB/octave pre-emphasis.
• G2B - phase-modulation with digital information and a sub-carrier for DSC operation.
• modulation index - the ratio between frequency deviation and modulation-signal frequency.

Who uses SIST EN 301 025-2:2001?

SIST EN 301 025-2:2001 is used by radio-equipment manufacturers, suppliers, compliance engineers, and test laboratories working on maritime VHF equipment. It is also relevant to quality managers and conformity assessors who need to verify spectrum use, transmitter purity, receiver selectivity and DSC performance before placing equipment on the market.

Which standards are used with SIST EN 301 025-2:2001?

• ETSI EN 301 025-1 - provides the technical characteristics and methods of measurement that this part references for definitions, limits and test methods.
• ETSI ETR 028 - gives the measurement uncertainty approach used for the compliance measurements.
• Directive 1999/5/EC - the R&TTE Directive, which is the regulatory basis for the harmonized standard.
• Council Directive 89/336/EEC - the EMC Directive named in the references.
• Council Directive 73/23/EEC - the Low Voltage Directive named in the references.
• Directive 98/34/EC - the information-procedure directive named in the references.

What does the SIST EN 301 025-2:2001 document contain?

SIST EN 301 025-2:2001 contains the conformance requirements for transmitter and receiver performance, plus the linked compliance tests. It includes a table of maximum absolute measurement uncertainties, which test labs use when evaluating results.

It also gives the essential radio test suites for transmitter frequency error, adjacent channel power, spurious emissions, transient behaviour, carrier power and frequency deviation, and the corresponding receiver and DSC tests. Clause 5 shows which test methods from Part 1 apply, so the document functions as a compliance map rather than a full measurement manual.

Annex A provides the EN-RT proforma for recording conformity against each requirement, which is useful for design reviews, test reports and certification files.
