Use the controls in the upper-right corner to maximize or
close the airView window.
You can place the cursor at a specific frequency to
highlight that frequency across the three spectral views,
each of which represents different data.
These are the three views:
• “Waveform View” on page 37
• “Waterfall View” on page 37
• “Ambient Noise Level” on page 37
Waveform View
This activity-based graph shows the aggregate energy
collected since the start of the airView session. The power
of the energy (in dBm) is shown across the frequency span.
Cooler colors (such as blue and darker colors) represent
energy of a specific strength and frequency appearing
at a relatively low occurrence rate, whereas increasingly
warmer colors (from green to yellow to orange to red)
represent energy of a specific strength and frequency
appearing at a higher rate of occurrence.
Note:
Energy is the power ratio in decibels (dB) of the
measured power referenced to one milliwatt (mW).
The spectral view over time essentially displays the steady-
state RF energy signature of a given environment.
The legend at the top-right corner provides a numerical
guide associating the various colors to probability levels,
from 0 (least likely to occur) to 1 (most likely to occur).
Waterfall View
This time-based graph shows the aggregate energy
collected since the start of the airView session for each
frequency. The power of the energy (in dBm) is displayed
across the frequency span, and a new row is inserted every
few seconds.
The energy color designates the amplitude (or strength)
of the signal. 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 legend at the top-right corner provides a numerical
guide associating the various colors to power levels (in
dBm). The low end of that legend (left) is always adjusted
to the calculated noise floor, and the high end (right) is set
to the highest detected power level since the start of the
airView session.
Ambient Noise Level
This time-based graph shows the ambient energy (in dBm)
as a function of frequency.
The energy color designates the amplitude (or strength) of
the ambient noise. 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 legend at the top-right corner provides a numerical
guide associating the various colors to power levels
(in dBm).
