Table 167: Swept Spectrogram 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 FFT power or duty cycles for a range of channels or frequencies. If you select Frequency, you must select the radio frequency on which this chart should center, and determine the span of frequencies for the graph. Channel Range Center Frequency If you selected Channel in the X-Axis parameter, you must also specify a channel range to determine which channels appear in the x-axis of this chart. Click the first drop-down list to select the lowest channel in the range, then click the second drop-down list to select the highest channel to appear in the chart. NOTE: This parameter is not configurable for graphs created by hybrid APs. If you selected Frequency in the X-Axis parameter, enter the frequency, in MHz, that you want to appear in the center of the x-axis of this chart. 815 | Spectrum Analysis Dell Networking W-Series ArubaOS 6.4.x | User Guide
