CWAP: Certified Wireless Analysis Professional v402 — Question 8

You are using the real-time FFT display of a spectrum analyzer.
In what domain does this show the RF energy detected in the swept frequencies?

Answer options

• A. Time
• B. Length
• C. Phase
• D. Frequency

Correct answer: C

Explanation

The correct answer is C, as the FFT (Fast Fourier Transform) display shows how energy varies with frequency. The other options, such as Time, Length, and Frequency, do not accurately represent the domain of RF energy as detected by the spectrum analyzer in this context.
