A unique feature of the transceiver is the ability to view the RF spectrum
above and below the operating frequency using its built-in Spectrum
Graph. Often, this can assist in diagnosing the cause of interference, or
to view other signals near your operating frequency.
To use the Spectrum Graph, you must first specify a center frequency
and a span frequency. The center frequency is the frequency that you
wish the spectrum display to be centered on. The span frequency defines
the width of the overall spectrum to be examined.
