This document presents a detailed test report for the HiFiMuse R20 Bluetooth device, conducted by Shenzhen Bangce Testing Technology Co., Ltd. The report verifies compliance with the requirements outlined in 47 CFR Part 15.247, focusing on frequency hopping systems. The tests performed include conducted emissions at the AC power line, maximum conducted output power, channel separation, number of hopping frequencies, dwell time, conducted band edge and spurious emissions, and radiated spurious emissions (both below and above 1 GHz).
The report provides comprehensive data and analysis, demonstrating that the HiFiMuse R20 meets the necessary regulatory standards. The test results indicate that the device complies with the specified limits for emissions and frequency hopping characteristics. The document includes detailed test setups, equipment lists, and graphical representations of the test data. The device was tested under various modes of operation, including GFSK, π/4 DQPSK, and 8DPSK modulations, to ensure thorough evaluation of its performance.
The test results confirm that the HiFiMuse R20 is suitable for its intended use and meets the regulatory requirements for Bluetooth devices operating in the 2402MHz to 2480MHz frequency band.
