Occupied Bandwidth
Occupied Bandwidth measures the power of the displayed frequency span and
displays vertical posts at the frequencies between which the specified percentage
of the power is contained. The frequency span between the two vertical posts is
the Occupied Bandwidth. The Occupied Power, the power that is contained
between the two posts, is also displayed in dBm.
