SIST ETS 300 067:1999/A1:1999 is the Slovenian adoption of an ETSI amendment for radiotelex equipment operating in the maritime MF/HF service. It updates the technical characteristics and methods of measurement by changing the adjacent channel selectivity test method. Manufacturers, test laboratories, and conformity assessors use it when checking receiver performance against the parent standard.

What does SIST ETS 300 067:1999/A1:1999 specify?

SIST ETS 300 067:1999/A1:1999 is an amendment to ETS 300 067 (1990), not a standalone product standard. Its scope is narrow: it improves the measurement method for adjacent channel selectivity because the earlier method caused difficulties in practice.

The document is organized as a short foreword, followed by amendment instructions that apply to one subclause of the parent standard. It also includes a brief history note. In practice, that means readers use this amendment together with ETS 300 067 when they need the corrected test setup.

What are the key requirements of SIST ETS 300 067:1999/A1:1999?

SIST ETS 300 067:1999/A1:1999 changes the adjacent channel selectivity measurement in subclause 5.3.2 of ETS 300 067. The practical effect is to simplify the interfering-signal setup so that the measurement is easier to carry out consistently.

Adjacent channel selectivity test signal

The amendment replaces the earlier unwanted-signal arrangement with an unmodulated RF signal. For test labs, this means the interfering source is a plain carrier, not a modulated waveform. That reduces setup complexity and avoids ambiguity in how the interfering signal is generated.

Text removed from the parent method

SIST ETS 300 067:1999/A1:1999 removes the description of the previous modulation chain for the unwanted signal. In practice, users should no longer apply the squarewave audio-frequency modulation arrangement described in the old text when performing this measurement.

Limited change to one subclause

The amendment affects only one subclause of the parent standard. That matters because implementers do not need to reinterpret the whole document - they apply the new adjacent channel selectivity method and keep the rest of ETS 300 067 as it stands.

Why the change matters

Adjacent channel selectivity checks how well radiotelex equipment rejects a signal in a neighboring channel. A clearer unwanted-signal definition makes the test easier to reproduce between laboratories and across manufacturers, which helps when comparing equipment performance.

What terms does SIST ETS 300 067:1999/A1:1999 define?

• Radiotelex equipment - Radio telex equipment used for maritime communications in the MF/HF service.
• Maritime MF/HF service - The maritime medium-frequency/high-frequency radio service covered by the standard.
• Adjacent channel selectivity - The receiver's ability to accept the wanted signal while rejecting a signal in a neighboring channel.
• Unwanted signal - The interfering signal applied during the measurement.
• RF signal - A radio-frequency signal used in the test setup.
• Unmodulated RF signal - An RF carrier without modulation, used here as the interfering signal.
• Unified Approval Procedure (UAP) - The ETSI approval route noted in the foreword for this amendment.

Who uses SIST ETS 300 067:1999/A1:1999?

SIST ETS 300 067:1999/A1:1999 is used by engineers, test laboratories, and compliance teams working with maritime radiotelex equipment. It is also relevant to manufacturers who need to design or verify receiver performance against the parent standard.

Quality managers and buyers can use it to understand what test method is expected when adjacent channel selectivity is evaluated. That matters when writing acceptance criteria, preparing test plans, or comparing offers for maritime communication equipment.

What changed in SIST ETS 300 067:1999/A1:1999 from the previous edition?

SIST ETS 300 067:1999/A1:1999 amends ETS 300 067 (1990). The change stated in the document is in subclause 5.3.2: the unwanted signal for adjacent channel selectivity measurement is changed from a frequency-modulated arrangement to an unmodulated RF signal, and the earlier squarewave audio-frequency modulation description is deleted.

Which standards are used with SIST ETS 300 067:1999/A1:1999?

• ETS 300 067 (1990) - The parent European Telecommunications Standard that this amendment modifies and with which it is used.

What does the SIST ETS 300 067:1999/A1:1999 document contain?

SIST ETS 300 067:1999/A1:1999 contains a foreword explaining that ETSI's Radio Equipment and Systems Technical Committee produced the amendment and that it was adopted under the UAP. It then gives direct amendment instructions for subclause 5.3.2, telling the reader exactly what text to delete and what to replace it with.

The document also includes a history note showing that it is an amendment to the first edition of ETS 300 067. For users, this means the document is mainly a targeted correction to the test method, not a full rewrite of the standard.
