SIST EN 60835-3-1:2002

SIST EN 60835-3-1:2002 is the Slovene adoption of IEC 60835-3-1 for methods of measurement used in digital microwave radio transmission systems, Part 3, Section 1. It gives general measurement methods for satellite earth station systems using digital modulation, for engineers and laboratories that need to assess their essential properties and associated sub-systems. The standard is meant to be used together with Part 1 for measurements that are common to both terrestrial radio-relay and satellite earth station systems.

What does SIST EN 60835-3-1:2002 specify?

SIST EN 60835-3-1:2002 specifies recommended measurement methods for satellite earth station systems using digital modulation. It focuses on the satellite earth station side of the work and points readers to Part 1 for measurements shared with terrestrial radio-relay systems.

The document is organised into the IEC foreword and preface, then:

• Clause 1 - Scope
• Clause 2 - Normative references

Clause 1 explains when to use Part 1 and when this part gives the satellite-specific detail. Clause 2 identifies the companion publication that this part depends on.

What are the key requirements of SIST EN 60835-3-1:2002?

SIST EN 60835-3-1:2002 sets out how to measure the essential properties of satellite earth station systems and the associated sub-systems. In practice, this means it is a measurement guide, not a product specification, and it tells users what method to apply when checking system performance.

1. Use it for satellite earth stations with digital modulation

Clause 1 says the methods apply to satellite earth station systems using digital modulation. That tells the reader the standard is aimed at digital radio transmission arrangements, not general analogue satellite links.

2. Treat it as supplementary to Part 1

Clause 1 says this part is supplementary to Part 1, IEC 835-1-1. In practice, a laboratory should not use this part alone when a measurement is common to both terrestrial radio-relay and satellite earth station systems.

3. Use Part 1 for shared measurements

Clause 1 says that where a measurement is common to terrestrial radio-relay and satellite earth station systems, the relevant section of Part 1 is used. This avoids repeating the same method in two places and helps users keep a single reference for shared test practice.

4. Use this part for satellite-specific aspects

Clause 1 says that only the special aspects appropriate to satellite earth station systems are described here. That matters because a user must look here when the measurement has a satellite-specific part, even if the basic method comes from Part 1.

5. Follow the full description when a parameter applies only to satellite earth stations

Clause 1 says parameters or methods that apply only to satellite earth stations are fully described in the relevant sections of this part. In practice, this is where a test engineer goes when the measurement is unique to satellite earth stations and not covered elsewhere.

6. Use it to assess essential properties

Clause 1 states that the object of the part is to provide recommended methods for assessing essential properties of satellite earth station systems and associated sub-systems. That tells users the document supports evaluation and verification work, especially in test and acceptance activities.

What terms does SIST EN 60835-3-1:2002 define?

The standard does not present a separate definitions clause in the provided text, but it uses several key terms consistently:

• Satellite earth station system - the satellite ground installation that the measurement methods are intended to assess.
• Digital modulation - the transmission method that places the standard in the digital radio domain.
• Associated sub-system - a part of the overall earth station arrangement that is measured along with the main system when relevant.
• Terrestrial radio-relay system - a system used as the comparison point for measurements that are common to both terrestrial and satellite use.
• Part 1, IEC 835-1-1 - the companion measurement standard that provides the shared methods referred to throughout this part.
• Normative references - the publication listed in Clause 2 that this part relies on for related measurement practice.

Who uses SIST EN 60835-3-1:2002?

SIST EN 60835-3-1:2002 is used by engineers, test laboratories, and technical committees working on radio relay and fixed-satellite communications systems. It is relevant when they need to choose the correct measurement method for a digital satellite earth station, especially when deciding whether to use the shared method from Part 1 or the satellite-specific treatment in this part.

Which standards are used with SIST EN 60835-3-1:2002?

The standard is intended to be used with Part 1, and its normative references point to the same companion publication for common measurements.

What does the SIST EN 60835-3-1:2002 document contain?

The document contains the IEC foreword and preface, which explain the consensus basis of the standard and its preparation by Sub-Committee 12E of IEC Technical Committee 12. It then gives the scope and the normative reference that links this part to Part 1. The structure shows that this is a general measurement section for satellite earth stations, with satellite-specific detail separated from the shared methods handled in the companion part.
