Channel Usage 

For each channel, a bar displays a 

percentage showing the relative “crowdedness” of 
that specific channel. To calculate this percentage, the 
airView Spectrum Analyzer analyzes both the popularity 
and strength of RF energy in that channel since the start 
of an airView session.

Note:

 airFiber X radio channels are not related 

to Wi‑Fi channels which are determined by IEEE 

standards. airFiber X radio channels are numbered 

consecutively starting with 0 and are 28 MHz in 
width.

Enable Waveform chart (middle) 

Check the box to 

enable the middle chart. This time‑based graph shows 
the RF signature of the noise environment since the 
start of the airView session. The energy color designates 
its amplitude. Cooler colors represent lower energy 
levels (with blue representing the lowest levels) in that 
frequency bin, and warmer colors (yellow, orange, or red) 
represent higher energy levels in that frequency bin.
The spectral view over time will display the steady‑state RF 
energy signature of a given environment.

Enable Real-time chart (bottom) 

Check the box to 

enable the bottom chart. This graph displays a traditional 
spectrum analyzer in which energy (in dBm) is shown in 
real time as a function of frequency. There are three traces 
in this view: 
• 

Current 

(Yellow) Shows the real‑time energy seen by 

the device as a function of frequency.

• 

Average 

(Green) Shows the running average energy 

across frequency.

• 

Maximum 

(Blue) Shows updates and maximum power 

levels across frequency.

Real-Time Traces

The following settings apply only to the 

Real-time

 chart:

Current Real-time Trace 

Check the 

Enable

 box to enable 

the real‑time trace. When enabled, the yellow outline on 
the 

Real-time

 chart represents the real‑time power level of 

each frequency. The refresh speed depends on the FPS.

Averages Trace 

Check the 

Enable 

box to enable the 

averages trace. When enabled, the averages trace is 
represented by the green area on the 

Real-time

 chart, 

which displays the average received power level data 
since the start of the airView session. To enable a shaded 
green area, check the 

Shaded Area

 box. To display only 

a green outline without the shaded area, uncheck the 

Shaded Area 

box.

Maximum Power Levels Trace 

Check the 

Enable 

box to 

enable the maximum power trace. When enabled, the 
maximum power trace is represented by the blue area on 
the 

Real-time

 chart, which displays the maximum received 

power level data since the start of the airView session. To 
enable a shaded blue area, check the 

Shaded Area 

box. 

To display only a blue outline without the shaded area, 
uncheck the 

Shaded Area 

box.

Frequency Range 

Select the amplitude of the 

frequency interval to be scanned from the 

Frequency 

Range

 drop‑down list. Available frequencies are device‑

dependent. There are pre‑defined ranges for the most 
popular bands. You can enter a custom range; select

Custom Range

 from the 

Frequency Range

 drop‑down list 

and enter the desired values in the 

Start

 and 

End

 fields.

Log

When logging is enabled (see 

“System Log” on page 

31

 for information on enabling the system log), this 

option lists all registered system events. By default, 
logging is not enabled.
