IEC 60489-6:1999 PDF

Overview

IEC 60489-6:1999 is an international standard developed by the International Electrotechnical Commission (IEC), titled Radio Equipment Used in Mobile Services - Methods of Measurement - Part 6: Data Equipment. This standard specifies methods for testing and measuring the radio-frequency performance of mobile radio transmitters and receivers designed for data (telegraphy) signal transmission. It builds upon the general framework found in IEC 60489-1 and helps ensure consistency and comparability in the type and acceptance testing of data communication equipment used in mobile radio services.

IEC 60489-6 focuses on the aspects unique to data equipment, covering various data signal formats such as bit streams, character strings, messages, and selective calling. By establishing uniform measurement techniques and terminology, this standard facilitates regulatory compliance, equipment validation, and interoperability within mobile data transmission systems.

Key Topics

• Scope and Application: Specifically addresses mobile radio transmitters and receivers intended for the transmission of data signals, including telegraphy and selective calling.
• Measurement Methods: Details procedures for testing key radio-frequency parameters, both for standard data communication and selective calling operations. These parameters include sensitivity, selectivity, spurious response immunity, and error ratios.
• Signal Types: Defines and distinguishes between bit streams, character strings, message formats, and selective calling, underpinning reliable data transmission over radio channels.
• Emission Characteristics: Covers types of modulation (e.g., amplitude, frequency, and phase modulation), information transmission formats, and relevant ITU emission designations.
• Test Conditions: Specifies standard and supplementary test conditions for consistent and reliable measurement outcomes, accommodating both terminal and integral-antenna equipment.
• Definitions and Terminology: Establishes precise terms and definitions, supporting clear communication and understanding between manufacturers, testers, and regulatory bodies.

Applications

• Mobile Radio Communication: Ensures that mobile data transmitters and receivers meet standardized performance criteria essential for reliable telegraphy and digital messaging in transportation, public safety, and commercial mobile radio networks.
• Type and Acceptance Testing: Supports product certification, regulatory approvals, and quality assurance for devices transmitting or receiving data over mobile radio channels.
• Interoperability Assessment: Facilitates meaningful comparisons between different equipment models and manufacturers by providing a uniform measurement framework and terminology.
• System Integration: As an integral part of the IEC 60489 standards series, IEC 60489-6 enables seamless integration of data communication capabilities within broader mobile communication infrastructures.
• Performance Verification: Assists engineers and testing laboratories in evaluating critical parameters such as error rates, signal sensitivity, selectivity, and response times under controlled and reproducible conditions.
