SIST EN 60835-2-4:2002

Overview

SIST EN 60835-2-4:2002 specifies standardized methods of measurement for equipment used in digital microwave radio transmission systems, specifically focusing on terrestrial radio-relay systems. This part of the standard applies to both transmitters (including modulators) and receivers (including demodulators), providing a reliable framework for assessing the performance of digital radio-relay systems. Adopting these testing and measurement practices is crucial for ensuring consistency, interoperability, and quality in modern telecommunications infrastructure.

Key Topics

The standard addresses several primary areas with respect to digital microwave radio transmission systems:

• Transmitter Measurements: Standardized methods to evaluate transmitter performance, including output power, frequency stability, and signal quality.
• Modulator Testing: Ensures that the modulation process conforms to required specifications for digital data transfer.
• Receiver Measurements: Enables accurate assessment of receiver sensitivity, selectivity, and distortion characteristics.
• Demodulator Performance: Outlines procedures to validate effective demodulation of incoming signals.
• Test Conditions and Procedures: Details the environmental and operational conditions under which measurements should be made for consistency and repeatability.

By focusing on these areas, SIST EN 60835-2-4:2002 helps organizations objectively assess system components and ensure robust service delivery.

Applications

Adhering to SIST EN 60835-2-4:2002 brings multiple practical benefits when working with digital microwave radio and terrestrial radio-relay systems:
