This document presents the findings of radiated emissions testing conducted on equipment operating within LTE Band 13, utilizing QPSK modulation. The tests were performed at channel bandwidths of both 5MHz and 10MHz, adhering to FCC regulatory requirements. The report details measurements taken at various harmonic frequencies to assess spurious emissions levels.
The testing setup included a range of calibrated instruments, such as the R&S CMW500 base station simulator, Keysight N9010A spectrum analyzer, and various antennas from Schwarzbeck and ETS-Lindgren. Measurements were recorded for both horizontal and vertical antenna polarizations to identify the worst-case emission scenarios. The data presented includes signal generator (SG) levels, cable losses, antenna gains, ERP levels, and margin relative to the FCC limits.
The results indicate that all spurious emissions were within the specified limits, with the worst-case emissions typically observed in the horizontal antenna polarization. Detailed tables provide a comprehensive overview of the measured values at each harmonic frequency, along with the corresponding azimuth angles. The report concludes that the equipment complies with the radiated emissions requirements for LTE Band 13 operation.
