Parameter Description
Band Radio band displayed in this graph.
For spectrum monitor radios using the 5 GHz radio band, click the Band drop-
down 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 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.
Center Frequency 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.
