This document presents a detailed test report, AiTSZ-250313053FW4, focusing on Band 4 performance. The report encompasses a range of tests, including Effective (Isotropic) Radiated Power (EIRP) output data, frequency stability assessments, modulation characteristics analysis, and bandwidth measurements (99% & 26dB). The tests were conducted under various network conditions, including RMC, HSDPA, and HSUPA, with different subsets to ensure comprehensive evaluation.
The EIRP tests provide insights into the radiated power output, ensuring compliance with regulatory limits. Frequency stability tests assess the device's ability to maintain a stable frequency under varying temperature and voltage conditions. Modulation characteristics are analyzed to verify the integrity of the transmitted signal. Bandwidth measurements, including Occupied Bandwidth (OBW) and 26dB Bandwidth (XDB), are performed to characterize the spectral occupancy of the device.
Furthermore, the report includes peak-average ratio measurements and spurious emission analysis, ensuring that the device meets stringent requirements for signal quality and unwanted emissions. All test results are presented with detailed graphs and tables, providing a clear and concise overview of the device's performance in Band 4.
