SIST ETS 300 454:1998/A1:1998 is the Slovenian adoption of ETS 300 454 Amendment 1 from ETSI. It covers Radio Equipment and Systems (RES) wide band audio links and updates the standard so it can be used as a harmonized standard linked to the EMC Directive and national type approval rules. Engineers, test laboratories, manufacturers, and approval bodies use it to see which transmitter and receiver parameters, bandwidth options, and documentation points matter in practice.

What does SIST ETS 300 454:1998/A1:1998 specify?

SIST ETS 300 454:1998/A1:1998 is an amendment to ETS 300 454 (1995) for wide band audio links in the 25 MHz to 3 GHz range. The amendment changes the foreword and adds two normative annexes that connect the technical standard to EMC-related compliance and to approval regulations.

The document is organized around the amended foreword, Annex D, and Annex E.

Annex	What it covers
Annex D	Clauses and subclauses of ETS 300 454 relevant for compliance with essential requirements of the EC Council Directives
Annex E	ERC Decision on the adoption of approval regulations for radio equipment used for wide band audio links in the 25 MHz to 3 GHz range

What are the key requirements of SIST ETS 300 454:1998/A1:1998?

SIST ETS 300 454:1998/A1:1998 does not rewrite the full technical standard here - it highlights the parts that matter for compliance, approval, and testing. The most useful points are the EMC-related clauses, the spectrum management parameters, and the permitted channel bandwidth options.

EMC-related clauses

Annex D identifies the clauses and subclauses relevant to compliance with the essential requirements of Council Directive 89/336/EEC. It points to transmitter spurious emissions in clause 8.4 and receiver spurious emissions in clause 9.1, and links them to article 4(a). In practice, this tells the reader which emission tests matter for the EMC-related part of conformity work.

Approval regulations for wide band audio links

Annex E contains the ERC Decision that calls for approval regulations for radio equipment used for wide band audio links in the 25 MHz to 3 GHz range. The decision is based on the limit values and measurement methods in ETS 300 454. For a manufacturer or approval body, this means the standard is not only a technical test document but also part of the route to national approval.

Parameters included in approval regulations

Annex E, Annex 1 lists the spectrum management parameters to be included in approval regulations. These include transmitter frequency error, carrier power, channel bandwidth, spurious emissions, transient frequency behaviour of the transmitter, and receiver spurious emissions definition and limits. In practice, these are the measurements that must be checked and documented when equipment is assessed for approval.

Channel bandwidth options

The ERC Decision recognizes channel bandwidth options of 50, 75, 100, 150, and 200 kHz. Annex 2 shows which administrations adopted which options. This matters when selecting equipment, setting up a system, or planning national deployment, because the permitted bandwidth must match the regulatory choice used in the target market.

National licensing matters

The decision also notes that some parameters are subject to national licensing requirements and may be excluded by national choice. It specifically refers to frequency of operation and equivalent isotropically radiated power (e.i.r.p.). In practice, users still need to confirm local frequency planning and licensing rules even when they follow ETS 300 454.

What terms does SIST ETS 300 454:1998/A1:1998 define?

• ETS - European Telecommunications Standard, the ETSI standard family used for harmonized technical rules.
• RES - Radio Equipment and Systems, the ETSI technical committee named in the document.
• ETSI - European Telecommunications Standards Institute, the body that produced and published the ETS.
• EMC Directive - Council Directive 89/336/EEC on electromagnetic compatibility, the directive referenced for harmonized compliance.
• CEPT - European Conference of Postal and Telecommunications Administrations, the organization whose administrations implement the approval decision.
• ERC - European Radiocommunications Committee, which issues the approval decision reproduced in Annex E.
• e.i.r.p. - equivalent isotropically radiated power, a licensing-related radio parameter mentioned in the decision.

Who uses SIST ETS 300 454:1998/A1:1998?

SIST ETS 300 454:1998/A1:1998 is used by manufacturers of wide band audio link equipment, including equipment for audio, data, and radio microphone applications. Test laboratories use it to set up measurements for transmitter and receiver emissions and other spectrum management parameters.

National administrations, approval authorities, and certification teams use it when preparing or checking approval regulations. Operators and buyers use it when they need equipment that matches the allowed bandwidth and licensing conditions in a target country.

What changed in SIST ETS 300 454:1998/A1:1998 from the previous edition?

SIST ETS 300 454:1998/A1:1998 is Amendment 1 to ETS 300 454 (1995). The amendment revises the foreword, adds the statement that the technical specifications relevant to the EMC Directive are listed in Annex D, and inserts normative Annex D and Annex E. It also adds the ERC Decision text that links ETS 300 454 to national approval regulations.

Which standards are used with SIST ETS 300 454:1998/A1:1998?

SIST ETS 300 454:1998/A1:1998 is used together with ETS 300 445, which the foreword names as part of the harmonized-standard package. The standard is based on CEPT Recommendation T/R 20-06, which the explanatory memorandum names as the technical basis for ETS 300 454. The ERC Decision also mentions CEPT Recommendation T/R 01-05 for transitional arrangements.

What does the SIST ETS 300 454:1998/A1:1998 document contain?

The document contains the amended foreword, a normative annex mapping ETS 300 454 clauses to EMC Directive relevance, and a normative annex reproducing the ERC Decision on approval regulations. Annex D provides the clause-to-directive table used for compliance work.

Annex E contains the full ERC Decision, its explanatory memorandum, and two annexes of its own. One annex lists the parameters to include in approval regulations, and the other shows national variations for channel bandwidth adoption. This makes the document useful for design checks, laboratory testing, and approval documentation.

EXPLANATORY MEMORANDUM
1. INTRODUCTION
The free movement of radiocommunications goods and the provision of Europe-wide services for
radiocommunications are only achievable if there exist common regulations throughout Europe regarding availability
of frequency bands, approval requirements and border crossing procedures. A basic requirement to fulfil these
objectives is the Europe-wide implementation of national regulations based on the European Telecommunications
Standards (ETSs) developed by the European Telecommunications Standards Institute (ETSI).
This Decision (ERC/DEC/(96)16) provides the necessary mechanism for CEPT Administrations to commit
themselves to implement, within their national regimes, European Telecommunications Standard 300 454 and
withdraw any conflicting national standard.
2. BACKGROUND
Both the ERC and ETSI are involved in the development of common regulations, as described in (1) above. The
Memorandum of Understanding between ERC and ETSI explains the respective responsibilities of the two
organisations and its annex describes the principles of co-operation. The ERC, for its part, should, inter alia,
