hi Jbrown,


In general 

Spectrum analysis provide  in depth radio frequency interference analysis and the signal level view of the RF medium . It  visualize  the RF activity on 2.4ghz and 5ghz including Noise and interference sources. 

It also provides the signal-level data and the impact of non-wifi device interference. spectrum analyzer is  to capture a representation of the signal energy (quality of the signal, signal strength, reflections, noise and interference)in graphic format

Let me know if you have a product specific query on spectrum analysis. 

Thanks 
Munish

Here are 2 APs that are fairly close together and this was from production hours.

Hi Jbrown,

It is showing the view of received signal power across the band and the color coded using signal power (-110 to -20dbm). Week signal is the blue ==> Red .

It also shows that Cumulative Distribution of received power across the band . <20% blue ==> 80% Week signal (Red)
