Description
If trace A is the source, a delta marker is set at the start and stop frequencies.
If 100% is specified, the power bandwidth equals the frequency range of the screen display. If
50% is specified, trace elements are eliminated from either end of the array, until the combined
power of the remaining signal responses equals half of the original power computed. The
frequency span of these remaining trace elements is the power bandwidth returned.
