This document summarizes the key findings of the Bluetooth DSS (Direct Sequence Spread Spectrum) testing performed by BLUE ASIA. The report, identified as BLA-EMC-202501-A7101, details the compliance of the device with relevant regulatory standards. The tests covered a range of parameters, including band edge performance, conducted RF spurious emissions, carrier frequencies separation, and the number of hopping channels.
The band edge analysis assessed the device's emissions at the edges of the allocated frequency bands, ensuring compliance with regulatory limits. Conducted RF spurious emissions were measured to verify that unwanted signals generated by the device were within acceptable levels. Carrier frequencies separation was evaluated to confirm that the device effectively utilizes frequency hopping to minimize interference. The number of hopping channels was also verified to meet the minimum requirement for Bluetooth devices.
The tests were conducted across different modes (1-DH1, 2-DH1, and 3-DH1) and frequencies (2402MHz, 2441MHz, and 2480MHz) to provide a comprehensive assessment of the device's performance. All test results indicate that the device meets the required specifications and passes the necessary compliance criteria.
