Band25 Conducted Spurious Emission Test Results

Appendix E: Conducted Spurious Emission Test Result Summary

Test Graphs Overview

The document contains numerous spectral plots illustrating conducted spurious emissions for various LTE Band 25 configurations. Each graph typically displays power levels across a frequency range, with markers indicating measured values and comparison to specified limits. The tests cover different bandwidths (1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz), modulations (QPSK and 16QAM), and resource block (RB) allocations (e.g., 1RB#0, 6RB#0, 15RB#0, 25RB#0, 49RB#0, 50RB#0, 74RB#0, 75RB#0, 99RB#0, 100RB#0) across various channels.

Key parameters observed in the graphs and associated tables include:

• Reference Level: Typically 30 dBm.
• Offset: Varies, e.g., 11 dB, 10.9 dB.
• Sweep: 10 of 10.
• RBW (Resolution Bandwidth): Varies, e.g., 14.00 k, 100.00 k, 30.00 k, 50.00 k, 150.00 k, 200.00 k (in kHz).
• VBW (Video Bandwidth): Varies, e.g., 3 kHz, 30 kHz, 300 kHz.
• Frequency Range: Specific start and stop frequencies for each test.
• Measured Power (PwrAbs [dBm]): The power level recorded at specific frequencies.
• Limit: The maximum allowed power level (▲ Limit [dB]).
• Verdict: Consistently 'PASS' for all presented results.

The graphs visually confirm that the spurious emissions are within the specified limits for the tested configurations.
