Figure 127 FFT Duty Cycle This chart shows the current duty cycle for devices on all channels being monitored by the spectrum monitor radio by default. Table 163 describes the other optional parameters you can use to customize the FFT Duty Cycle table. Click the down arrow in the upper right corner of this chart, then click the Options menu to access these configuration settings. Once you have configured the desired parameters, click OK at the bottom of the Options menu to save your settings and return to the spectrum dashboards. Table 163: FFT Duty Cycle Options Parameter Description Band Radio band displayed in this graph. For spectrum monitor radios using the 5 GHz radio band, click the Band dropdown list and select 5 GHz upper, 5GHz middle or 5Ghz lower to display data for that portion of the 5 Ghz radio band. This parameter is not configurable for graphs created by hybrid APs or spectrum monitor radios that use the 2.4 GHz radio band. Channel Numbering This parameter is not configurable for graphs created by hybrid APs or spectrum monitor radios that use the 2.4 GHz radio band. A hybrid AP on a 20 MHz channel sees 40 MHz Wi-Fi data as non-Wi-Fi data. For spectrum monitors using the 5 GHz radio band, click the Channel Numbering drop-down list and select either 20 MHz or 40 MHz channel numbering to identify a channel numbering scheme for the graph. Graphs for AP radios that support 802.11ac include an additional 80MHz option for very-high-throughput channels. X-Axis Select either Channel or Frequency to show the duty cycle for a range of channels or frequencies. Dell Networking W-Series ArubaOS 6.4.x | User Guide Spectrum Analysis | 806
