This document presents a comprehensive test report from the ADR Test and Certification Center, focusing on the band edge compliance of a device operating in the DC_5A_n66A band. The report, identified by number TR-25ADRTCC7007, details various tests conducted to ensure the device adheres to regulatory standards regarding spurious emissions and signal integrity at the band edges.
The tests cover different modulation schemes, including DFT-Pi2BPSK, DFT-QPSK, CP-QPSK, CP-16QAM, CP-64QAM, and CP-256QAM, under varying bandwidth configurations (5MHz, 10MHz, and 15MHz). Each test scenario is meticulously documented with spectrum analyzer plots, showing the signal behavior at the band edges. The plots include limit lines, marker readings, and tabular data indicating frequency, power levels, and compliance margins.
The report provides a detailed analysis of the device's performance, confirming its adherence to regulatory limits and ensuring minimal interference with adjacent frequency bands. The data presented is crucial for certification purposes and demonstrates the device's suitability for operation within the specified frequency range.
