Dell 6.2 manual Axis, Frequencies for the graph

NOTE: This chart is not available for W-AP120 Series or W-AP68 access points. A hybrid AP on a 20 MHz channel will see 40 MHz

Wi-Fi data as non-Wi-Fi data.

This chart can show an average for all samples taken over the last second, the maximum FFT power measured for all samples taken over ten channel sweeps, and the greatest FFT power recorded since the chart was last reset. When you hover your mouse over any line, a tooltip shows the power level and channel or frequency level represented by that point in the graph. When you hover your mouse over a frequency level (within the blue brackets on the graph), a tooltip shows the types of devices seen on that frequency, as well as each device’s BSSID, power level, channels affected and the time the device was last seen by the spectrum monitor.

Figure 227: Real-TIme FFT

By default, this chart shows the maximum power level recorded for any device on all channels or frequencies monitored by the spectrum monitor radio.

Table 228 describes the other parameters you can use to customize the Real-time FFT chart. 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.

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 lowerto 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	For spectrum monitors using the 5 GHz radio band, select either 20 MHz or 40 MHz channel numbering to
Numbering	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. A hybrid AP on a 20 MHz channel sees 40 MHz Wi-Fi data as non-Wi-Fi data.
X-Axis	Select either Channel or Frequency to show FFT power 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	If you selected Channel in the X-Axisparameter, you must also specify a channel range to determine which
Range	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.
