FFT Duty Cycle
The FFT Duty Cycle chart is a line chart that shows the duty cycle for eachfrequency bin. The width of the each
frequencybin depends on the resolution bandwidth of the spectrum monitor. The spectrum analysis feature
considers a frequencybin to be utilized i f the detected power in that bin is at least 2 0 dB higher than the nominal
noise floor on that channel. The FFT Duty Cycle provides a more granular view of the duty cycle per bin as opposed
to the aggregatedchannel utilization reported in the Channel Metrics chart.
NOTE:Thi s charti s not available for W-AP120 Series or W-AP68 access points. A hybrid AP on a 20 MHz channel wi ll see 40 MHz
Wi-Fi dataas non-Wi-Fi data.
This chart can show the duty cycle over thelast seco nd,the maximum FFT duty cycle measured for allsamples
taken overt helast N sweeps, and the greatest FFT duty cycle recorded since the chart was last reset.
