This document presents the appendix report for Bluetooth (TWS) testing conducted by BANGCE. The report details various tests performed to ensure compliance with regulatory standards, focusing on key parameters such as duty cycle, 20dB bandwidth, carrier frequencies separation, and out-of-band emissions. The tests were conducted on different modulation schemes, including GFSK, π/4DQPSK, and 8DPSK, using various packet types like DH5, 2-DH5, and 3-DH5.
The report includes detailed test results, accompanied by graphical representations of the data. The duty cycle measurements provide insights into the transmission characteristics of the device, while the 20dB bandwidth analysis ensures that the signal occupies the appropriate frequency range. Carrier frequencies separation tests verify the device's ability to hop between channels effectively, and out-of-band emission tests confirm that the device does not generate excessive spurious signals outside the intended frequency band.
All tests were performed according to established methodologies, and the results indicate that the device meets the required specifications. The report provides a comprehensive overview of the Bluetooth (TWS) testing process and serves as evidence of compliance with relevant regulatory standards. The certification number associated with this report is CISR250415138.
