This document presents a detailed test report (AiTSZ-250313053FW5) focusing on the effective (isotropic) radiated power (EIRP), frequency stability, and bandwidth characteristics of a device operating in Band 4. The report covers various bandwidth configurations, including 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz, under NTNV conditions.
The testing methodology encompasses measurements of conducted power, antenna gain, and resulting EIRP, ensuring compliance with regulatory limits. Modulation schemes such as QPSK and 16QAM are evaluated across different RB allocation sizes and offsets. Frequency stability is assessed under varying temperature and voltage conditions, with results presented in terms of frequency error (Hz) and frequency vs. rated (ppm).
Furthermore, the report includes detailed bandwidth measurements, specifically 99% occupied bandwidth (OBW) and 26dB bandwidth (XDB), providing insights into the spectral occupancy of the device. Modulation characteristics are visually represented through constellation diagrams, confirming the integrity of the transmitted signals. All test results are meticulously documented, with verdicts indicating whether the device passes or fails each test based on predefined limits.
