This report presents the results of conducted spurious emission testing performed on a device operating in LTE Band 2. The tests were conducted in accordance with ANSI C63.26:2015 and FCC regulations, specifically parts 22.913(a), 24.238(a), and 27.53(h). The primary objective was to assess the device's compliance with out-of-band emission limits at the antenna terminals.
The testing encompassed various channel bandwidths, including 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz, with different resource block (RB) allocations such as 1RB, 6RB, 15RB, 25RB, 50RB, 75RB, and 100RB. Measurements were taken at the lowest, middle, and highest channels within the LTE Band 2 frequency range. The RF output of the transceiver was connected to a spectrum analyzer through appropriate attenuation, and the spectrum was analyzed up to the 10th harmonic.
The spectrum analyzer settings were carefully configured to capture and analyze spurious emissions, with a resolution bandwidth of 1MHz and a video bandwidth of 3MHz. The results presented in this report demonstrate the device's performance in terms of conducted spurious emissions across different operating configurations.
