Overview
IEC 61196-1-107:2005 is an international standard published by the International Electrotechnical Commission (IEC) that specifies electrical test methods for coaxial communication cables. This particular part of the IEC 61196 series focuses on assessing the microphony charge level, also known as mechanically induced noise, within coaxial cables. The standard establishes a test method to measure noise generated in cables when subjected to mechanical stress, which is critical for ensuring signal integrity in communication systems.
The standard applies specifically to coaxial communications cables and provides a detailed procedure for testing the microphony characteristic. This helps manufacturers and users evaluate how physical handling, bending, or vibrations affect cable performance by inducing noise that can degrade signal quality.
Key Topics
-
Scope and Application
The standard covers coaxial communication cables and the electrical testing required to determine the level of noise generated by mechanical actions on the cable.
-
Test Procedure
It details the preparation of cable specimens, appropriate test equipment setups, and the step-by-step procedure to induce mechanical stresses such as elongation and vibration.
-
Measurement Conditions
Specifies environmental and mechanical parameters required for consistent and reproducible results, including cable fixation, mechanical preload, elongation, and resonance considerations.
-
Noise Measurement and Expression
Defines how to quantify and express the microphony charge level resulting from mechanical stress, ensuring reliable measurements of mechanically induced noise.
-
Precautionary Measures
Emphasizes measurement precautions to avoid artifacts, including the management of earth loops and ensuring reproducibility of test results.
-
Reporting and Requirements
Outlines how to document test results comprehensively and specifies performance requirements or limits for cable microphony levels.
Applications
This standard is crucial for:
- Cable Manufacturers: To evaluate and control the quality of coaxial cables, minimizing mechanically induced noise that can impair signal transmission.
