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. The repeatability of your band power marker measurement can be
impacted by the current number of sweep points being used. If you only have a
few sweep points in the measurement band of interest, then small changes will
have a direct impact on the measurement result. Increasing your number of
sweep points will decrease that affect and improve the repeatability.
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.
Remarks: If a marker is not active when the mode is queried, “Off” will be
returned.

Define Peak Excursion
:CALCulate:MARKer:PEAK:EXCursion <rel_ampl>
: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.)
