This document presents a detailed test report from ADR Test and Certification Center, focusing on the spurious emissions and frequency stability of a device operating in the NR Band DC_4A_n2A (1850-1910 MHz). The report, identified as TR-25ADRTCC7007, includes comprehensive data and analysis to ensure compliance with regulatory standards.
The report includes spectrum plots illustrating spurious emissions for various configurations, including MCH and LCH channels with DFT-Pi2BPSK and DFT-QPSK modulations, using Edge_1RB_Left resource block allocation. Each plot details the frequency range, RBW, power levels, and ALimit values, ensuring thorough coverage of potential spurious signals.
Furthermore, the report presents frequency stability test results, examining frequency error variations against voltage and temperature changes. The data includes deviation results in both Hertz (Hz) and parts per million (ppm), along with a verdict indicating whether the device passes the stability requirements. This comprehensive testing ensures the device's reliable operation under varying environmental conditions.
