:CALCulate:MARKer:PEAK:EXCursion?
Specifies the minimum signal excursion above the threshold for the
internal peak identification routine to recognize a signal as a peak. This
applies to all traces and all windows. (The excursion is the delta power
from the noise level to the signal peak.)

Position selects a normal marker that can be positioned on a trace
and from which trace information will be generated.
Delta activates a pair of markers, one of which is fixed at the current
marker location. The other marker can then be moved around on the
trace. The marker readout shows the difference between the two
markers.
Band activates a pair of band markers, where each marker can be
independently positioned on the trace. The marker readout shows
the difference between the two markers.
Span activates a pair of span markers, where the marker positioning
is controlled by changing the span and/or center frequency between
the two markers. The marker readout shows the difference between
the two markers.
