Configuring channels to simulate intended signal quality

Testing the RF performance of 5G New Radio (NR) networks requires measuring key performance metrics such as error vector magnitude (EVM) to assess the quality of transmitted signals. To get meaningful measurements, engineers must configure the analysis to reflect the intended transmitter channel and the signal quality. This process enables engineers to verify synchronization, assess power levels, analyze signal structure, and validate baseband processing.

The first step is verifying the correlation metrics using synchronization signals to ensure accurate and reliable results. The second step is checking the transmitted power using the resource element (RE) power to confirm the expected power level. Engineers need to analyze the transmitted signal’s structure and quality and isolate impaired signals. Finally, engineers need to run cyclic redundancy checks to confirm successful measurement results.

5G NR measurement solution

Optimizing 5G NR signal quality and performance requires tools that can accurately reflect real-world conditions. The Keysight PathWave vector signal analysis (89600 VSA) software’s design achieves low EVM and validates the correct coding of physical channels in 5G NR transmissions. The PathWave VSA software solution provides comprehensive flexibility in configuring analysis parameters to match the intended transmitter channel configuration and ensure precise measurements. The 5G NR test solution enables engineers to verify sync correlation metrics, analyze transmitted power levels, examine signal structure, and isolate signal impairments using coupled markers. Additionally, confirming successful EVM results and validating baseband processing with cyclic redundancy checks (CRC) ensures that both the RF and baseband components function correctly, leading to high-quality, reliable 5G NR communications.
