SIST ETS 300 086:1998/A1:1998

SIST ETS 300 086:1998/A1:1998 is the Slovene adoption of ETS 300 086 Amendment 1 from ETSI for land mobile radio equipment with an internal or external RF connector intended primarily for analogue speech. It updates the parent standard’s test conditions for extreme temperature operation and the measurement arrangement used in one transmitter test, so manufacturers, test laboratories and licensing authorities can apply the same technical basis.

What does SIST ETS 300 086:1998/A1:1998 specify?

SIST ETS 300 086:1998/A1:1998 is an amendment to ETS 300 086 (1991). It changes the foreword, subclause 5.4.1 and subclause 7.7.2 of the parent standard, and it ties one measurement arrangement to I-ETS 300 113.

In practice, the amendment is focused on two areas: environmental testing at extreme temperatures and the test setup used for a transmitter-related measurement. The document itself is organized as the foreword, the amendment instructions, and a short history section.

What are the key requirements of SIST ETS 300 086:1998/A1:1998?

• The foreword states that angle modulation is used for the equipment covered by the ETS, while national administrations may choose the modulation type for their own licensing rules. In practice, a manufacturer still has to check local spectrum or radio licence conditions before placing equipment on a market.

• The foreword also notes that channel separations, maximum transmitter output power or effective radiated power (ERP), transmitter intermodulation attenuation, and an automatic transmitter shut-off facility may be licence conditions. For users, this means product design and deployment can depend on the administration’s operating rules, not only on the equipment standard.

• Subclause 5.4.1 updates the extreme-temperature test conditions. Measurements are to be made using the procedure in subclause 5.5 at the upper and lower ends of the range from -20 °C to +55 °C, and the reduced range of 0 °C to +30 °C is used when the note to table 1 in 4.1.1 applies. This matters because the chosen temperature range changes the test plan and the environmental chamber settings.

• Subclause 5.4.1 also requires type test reports to state which temperature range was used. That gives traceability for certification, audits and later product comparisons.

• Subclause 7.7.2 replaces figure 2 with the measurement arrangement taken from figure 11 of I-ETS 300 113. The arrangement uses an interfering transmitter, the equipment under test, a test signal source, 50 ohm termination and attenuation, and a spectrum analyser, which means the physical bench setup is part of the measurement result.

What terms does SIST ETS 300 086:1998/A1:1998 define?

• Radio Equipment and Systems (RES) - ETSI’s radio standards area named in the title and foreword.
• RF connector - the radio frequency connection point on the equipment under test.
• analogue speech - voice transmission in analogue form, which is the intended primary use of the equipment.
• angle modulation - the modulation method mentioned in the foreword for equipment covered by the ETS.
• effective radiated power (ERP) - a transmitter power measure that administrations may use as a licence condition.
• automatic transmitter shut-off facility - a feature that can stop transmission automatically if required by the administration.
• type test report - the report that records the test conditions used, including the temperature range.

Who uses SIST ETS 300 086:1998/A1:1998?

Manufacturers of land mobile radio equipment use it when designing and type-testing products with internal or external RF connectors. Test laboratories use it to set environmental conditions and measurement benches. National administrations and licensing authorities use the foreword’s points when setting operating conditions such as power, channel spacing and transmitter controls. Quality managers, conformity assessors and buyers use it to check that the equipment and test plan match the intended analogue speech application.

What changed in SIST ETS 300 086:1998/A1:1998 from the previous edition?

SIST ETS 300 086:1998/A1:1998 amends ETS 300 086 (1991). The changes stated in the amendment are the updated foreword text on modulation and licence conditions, the new extreme-temperature test range rules in subclause 5.4.1, the requirement for type test reports to state the range used, and the replacement of figure 2 in subclause 7.7.2 with the specified measurement arrangement.

Which standards are used with SIST ETS 300 086:1998/A1:1998?

• ETS 300 086 (1991) - the parent standard that this amendment modifies.
• I-ETS 300 113 - the source of the replacement measurement arrangement used in subclause 7.7.2.

What does the SIST ETS 300 086:1998/A1:1998 document contain?

The document contains the amendment front matter, the foreword, the list of affected pages and subclauses, and a short history section. Its technical content is limited to the revised extreme-temperature test clause and the revised measurement arrangement figure. For readers, that means it is meant to be applied together with ETS 300 086 rather than used as a stand-alone full standard.
