Spectrum Analysis

Context

The AP3010DN-AGN and AP9330DN do not support this function.

On the Spectrum Analysis page, you can enable or disable the spectrum analysis function on a radio and view spectrum charts. The Spectrum Analysis page can display eight types of spectrum charts, including Swept Spectrogram, Active Devices, Real-Time FFT, Channel Metrics, Channel Quality Trend, FFT Duty Cycle, Interference Power, and Quality Spectrogram.

Procedure

Enable spectrum analysis on a radio and view spectrum charts.

Choose Monitoring > Wireless Service > Spectrum Analysis. The Radio List page is displayed.
