Meaning
Specific absorption rate measurement protocols require uniform procedures to ensure consistency across different test laboratories. The publication designated KDB 865664 D01 outlines the reporting requirements and the measurement systems used for compliance tests. This reference covers frequencies from three to six gigahertz where tighter grid resolutions and smaller probe steps are necessary.
It provides the reference guidelines for tissue simulating liquids, validation requirements, and uncertainty analyses.
System Validation
Annual system validations ensure that the measurement hardware and software produce repeatable results within established margins. Under KDB 865664 D01, these checks require dipole antennas to be placed beneath the reference phantoms. The recorded values must fall within ten percent of the target values specified in the database.
This procedure detects component degradation or liquid contamination before testing begins.
Grid Resolution
High frequency evaluations demand smaller step sizes to accurately resolve localized peak absorption points. The guidelines in KDB 865664 D01 mandate specific horizontal and vertical grid steps during area and zoom scans. These strict steps ensure that the interpolation algorithms do not miss the highest absorption region.
This precision is necessary because higher frequencies attenuate faster in biological tissues.
Compliance Reporting
Technical reports must document all system parameters and measurement files in a standardized format. Compliance with KDB 865664 D01 remains a prerequisite for completing the administrative filing process with telecommunications certification bodies.
