This document presents a comprehensive analysis of FCC-BT appendix data conducted by Anbotek Compliance Laboratory. The report includes detailed measurements and analysis related to various Bluetooth testing parameters, ensuring compliance with FCC regulations.
The data encompasses bandedge measurements, assessing the signal strength at the edge of the allocated frequency band to prevent interference with adjacent channels. Carrier frequency separation analysis is performed to verify the proper spacing between hopping channels, a crucial aspect of frequency-hopping spread spectrum (FHSS) systems. The number of hopping channels is also evaluated to ensure sufficient channel diversity.
Furthermore, the document provides an in-depth examination of dwell time, measuring the duration a device occupies a specific channel during a hopping sequence. This parameter is critical for maintaining efficient spectrum utilization and minimizing potential interference. The analysis covers different modulation schemes and packet types, providing a thorough assessment of the device's Bluetooth performance.
