This report, identified as BLA-EMC-202503-A2703, details the testing procedures and results for the DFS (Dynamic Frequency Selection) non-occupancy period. The testing was conducted by Blue Asia and adheres to the standards set forth in 47 CFR Part 15, Subpart E 15.407(h)(2) and KDB 905462 D02 Section 7.8.3. The primary objective was to verify that the device under test (DUT) does not re-occupy a channel after a radar signal is detected, ensuring compliance with regulatory requirements.
The report outlines the test setup, which includes an RF test system with components like a CMW500, spectrum analyzer (SA), PSG, ASG, and a programmable power supply. The procedure involves generating radar pulses at the operating frequency of the master and client devices, simulating a radar event. The DUT's behavior is then monitored for a specified period (minimum 30 minutes) to confirm that no transmissions or beacons occur on the channel after the radar signal is detected. The report also includes duty cycle measurements for various modes and frequencies, providing a comprehensive overview of the device's performance under DFS testing conditions.
