SIST EN 300 341-2:2001

SIST EN 300 341-2:2001 is a SIST publication of ETSI EN 300 341-2 for land mobile radio equipment that uses an integral antenna to transmit signals that initiate a specific response in the receiver. It is the harmonized EN under article 3.2 of the R&TTE Directive, so it is used to assess whether this kind of radio equipment uses spectrum in a way that avoids harmful interference.

What does SIST EN 300 341-2:2001 specify?

SIST EN 300 341-2:2001 specifies the radio-spectrum requirements for constant envelope angle modulation systems used in the land mobile service, with operating frequencies from 30 MHz to 1000 MHz and channel separations of 12,5 kHz, 20 kHz and 25 kHz. It applies to non-speech transmissions and to the non-speech part of combined speech/non-speech equipment with integral antennas.

The document is organized into these main clauses:

• Clause 1 - Scope
• Clause 2 - References
• Clause 3 - Definitions, symbols and abbreviations
• Clause 4 - Technical specifications
• Clause 5 - Testing for compliance with technical requirements

The equipment may include a transmitter with an encoder, or a receiver with a decoder, and compliance covers the equipment combination when the encoder or decoder is separate.

What are the key requirements of SIST EN 300 341-2:2001?

SIST EN 300 341-2:2001 sets out the spectrum and receiver-performance checks that support article 3.2 of the R&TTE Directive. In practice, it tells manufacturers and test labs what to measure, which companion clauses in EN 300 341-1 to use, and how to report the results.

Radio performance limits and methods

Clause 4.2 covers the core transmitter and receiver characteristics. For each item, the document gives the definition, points to the limit in EN 300 341-1, and points to the measurement method in EN 300 341-1 or, for one item, within this part.

The covered items are:

• transmitter frequency error
• effective radiated power
• adjacent channel power
• transmitter radiated spurious emissions
• transient frequency behaviour of the transmitter
• average usable sensitivity
• co-channel rejection
• adjacent channel selectivity
• spurious response rejection
• intermodulation response rejection
• blocking or desensitization
• receiver spurious radiations

For a reader, this means the standard is not just about transmitter power. It also checks how cleanly the signal stays in its assigned channel and how well the receiver handles unwanted signals.

Test conditions and compliance assessment

Clause 5.1 says testing is done under normal test conditions and, where EN 300 341-1 requires it, under extreme test conditions. This matters because compliance has to reflect real operating conditions, not only ideal bench setup.

Clause 5.2 requires the measured value to be compared with the relevant limit and requires measurement uncertainty to be reported in the test report. It also ties the uncertainty calculation to ETR 028 and states that the uncertainty values shall not exceed the figures in the table in this clause.

Test suites

Clause 5.3 lists the essential radio test suites for transmitter checks, and clause 5.4 lists the other radio test suites used to assess receiver performance. This gives laboratories a direct test structure for conformity assessment and type testing.

What terms does SIST EN 300 341-2:2001 define?

• Non-speech radio equipment - radio equipment that transmits a signal to initiate a specific response in the receiver.
• R&TTE - the Radio and Telecommunications Terminal Equipment Directive named in the scope and references.
• EMC - electromagnetic compatibility, the subject area covered by the European EMC Directive named in the references.
• LV - low voltage, referring to the Low Voltage Directive named in the references.
• Transmitter frequency error - the deviation of the transmitted frequency from its intended value.
• Effective radiated power - the radiated power from the transmitter as assessed by the standard’s measurement method.
• Adjacent channel power - unwanted power falling into neighboring channels.
• Blocking or desensitization - a receiver’s loss of sensitivity when exposed to strong interfering signals.

Who uses SIST EN 300 341-2:2001?

Manufacturers of land mobile radio equipment use SIST EN 300 341-2:2001 when designing products with integral antennas and non-speech signalling functions. Test laboratories use it to run the transmitter and receiver measurements and to prepare compliance reports.

It is also used by quality managers, regulatory teams, and conformity assessment staff who need to show that the equipment meets the spectrum-use requirements linked to the R&TTE Directive. Buyers and integrators can use it to check whether a product family is covered by the right harmonized standard.

Which standards are used with SIST EN 300 341-2:2001?

• Directive 1999/5/EC - the R&TTE Directive that gives the legal article 3.2 requirement this standard addresses.
• ETSI EN 300 341-1 - provides the technical characteristics, definitions, limits and measurement methods that Part 2 references throughout.
• ETSI ETR 028 - provides the approach for calculating measurement uncertainty.
• Council Directive 89/336/EEC - the EMC Directive named in the references.
• Council Directive 73/23/EEC - the LV Directive named in the references.
• Council Directive 98/34/EC - the notification procedure referenced in the foreword.

What does the SIST EN 300 341-2:2001 document contain?

The document contains the scope, referenced documents, shared definitions and abbreviations, then the technical specifications for transmitter and receiver performance. It also contains the compliance-testing rules, including test conditions, how to interpret results, and how to handle measurement uncertainty.

Clause 4 gives the list of radio performance items to be checked, while clause 5 gives the test suites for transmitter frequency error, radiated emissions, receiver sensitivity and rejection behaviour. The document also includes a table of maximum absolute measurement uncertainties for different RF and receiver parameters, which is used when preparing test reports.
