Dell 6.2 manual Working with Non-Wi-Fi Interferers

Parameter	Description
	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	For spectrum monitors using the 5 GHz radio band, select either 20 MHz or 40 MHz channel
	numbering to identify a channel numbering scheme for the graph.
	NOTE: This parameter is not configurable for graphs created by hybrid APs or spectrum monitor
	radios that use the 2.4 GHz radio band.
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-Axisparameter, 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-Axisparameter, enter the frequency, in MHz, that you want to
	appear in the center of the x-axis of this chart.
Span	If you selected Frequency in the X-Axisparameter, specify the size of the range of frequencies
	around the selected center frequency. If you set a frequency span of 100 MHz, for example, the
	chart shows the swept spectrogram for a range of frequencies from 50MHz lower to 50 MHz
	higher than the selected center.
Color-Map Range	If this chart is configured to show average or maximum FFT values, the default color range on
	this chart represents values from -50dBm (red) to -90dBm (blue). If you would like the color range
	on this chart to represent a different range of FFT power levels, enter this range in the from and
	to entry blanks.
	For example, if you defined a color-map range from -60 to -80, then any FFT power level at or
	above -60 dBm would appear as red, and any FFT power level at or below -80 would appear
	blue. Only the channel or frequency qualities between -60 dBm and -80 dBm would be
	represented by gradiented colors within the color range.
	If this chart is configured to show the FFT duty cycle, the default color range on this chart
	represents duty cycles from 0% (red) to 100% (blue). If you would like the color range on this
	chart to represent a different range of FFT duty cycle percentages, enter this range in the from
	and to entry blanks.
	For example, if you defined a color-map range from 25 to 75, then any FFT duty cycle at or below
	25% would appear as red, and any FFT duty cycle at or below 75% would appear blue. Only the
	duty cycle levels between 25% and 75% would be represented by gradiented colors within the
	color range.
	NOTE: If your swept spectrogram is showing a single color only, you may need to increase the
	color map range to display a greater range of values.
Show	Select FFT Avg, FFT Max or FFT Duty Cycle to select the type of data you want to appear in this
	chart.
