Which tool is commonly recommended to monitor frequency usage in order to minimize RF interference during sUAS operations?

• A. Handheld radio scanner with spectrum monitoring
• B. Spectral analyzer
• C. Oscilloscope
• D. GPS receiver

Answer: (B)

Monitoring frequency usage effectively hinges on seeing how the RF spectrum looks across the bands you plan to use. A spectral analyzer provides a real-time, broad view of the spectrum, showing how much energy is present at each frequency, which channels are actually occupied, and where spurious signals or harmonics show up. With that information you can pick a clean channel, gauge the likelihood of interference, and adjust transmitter settings or flight plans to minimize risk during the operation. Other tools don’t give this full picture: a handheld scanner tends to monitor only a limited set of preselected channels and won’t show the overall spectrum, an oscilloscope looks at time-domain signals rather than their frequency distribution, and a GPS receiver has no role in assessing RF spectrum usage.
