Note: This feature is experimental, and many updates are expected for it, as well as for this document. The spectrum analyzer can scan all frequencies supported by your wireless card, and plot them directly in console. Exact frequency span depends on card. Allowed ranges on r52n: [4790; 6085], [2182; 2549]. Wireless card can generate 4us long spectral snapshots for any 20mhz wide channel. This is considered a single spectral sample. To improve data quality spectrum is scanned with 10mhz frequency increments, which means doubled sample coverage at each specific frequency (considering 20mhz wide samples). Currently this feature is supported only for Atheros Merlin chips. (ie. AR9220, AR9280, AR9223). Currently tested models: RouterBOARD R52N and R2N only. Plots spectrogram. Legend and frequency ruler is printed every 24 lines. Numbers in the ruler correspond to the value at their leftmost character position. Power values that fall in different ranges are printed as different colored characters with the same foreground and background color, so it is possible to copy and paste terminal output of this command. Continuously monitor spectral data. This command uses the same data source as 'spectral-history', and thus shares many parameters. Each line displays one spectrogram bucket -- frequency, numeric value of power average, and a character graphic bar. Bar shows average power value with ':' characters and average peak hold with '.' characters. Maximum is displayed as a lone floating ':' character. Types of possibly classified interference:Console
