:CALCulate :MARKer :PEAK :E%Cursion ?
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 .)

:CALCulate :MARKer :PEAK :SEARch :MODE ?
Sets the peak search mode .
NOTE
See command :
CALCulate :MARKer [ 11 ~ 2 ~ 3 ~ 4 :MASimum
Factory Prese t
and *RST: MAXimum
Remarks: If mode is set to MAXimum, peak search will place th e
marker at the maximum amplitude in the trace . If
mode is set to PARameter, peak search will place the
marker at the highest peak that rises and falls by a t
least the peak excursion above the peak threshold. If n o
peak meets the excursion and threshold criteria, a N o
Peak Found error (error 202) is issued .
Next peak, next peak right, next peak left, and peak
table are not affected by this command. They will
always use peak excursion and peak threshold fo r
search criteria.
