"On"
The minimum frequency included in the peak search range is ≥ 5 ×
resolution bandwidth (RBW).
Due to the interference by the first local oscillator to the first inter-
mediate frequency at the input mixer, the LO is represented as a sig-
nal at 0 Hz. To avoid the peak marker jumping to the LO signal at 0
Hz, this frequency is excluded from the peak search.
"Off"
No restriction to the search range. The frequency 0 Hz is included in
the marker search functions.
Remote command:
CALCulate<n>:MARKer<m>:LOEXclude on page 990
Peak Excursion
Defines the minimum level value by which a signal must rise or fall so that it is identi-
fied as a maximum or a minimum by the search functions.
Entries from 0 dB to 80 dB are allowed; the resolution is 0.1 dB. The default setting for
the peak excursion is 6 dB.
For analog demodulation, the unit and value range depend on the selected result dis-
play type.

Auto Max Peak Search / Auto Min Peak Search
If activated, a maximum or minimum peak search is performed automatically for
marker 1 after each sweep.
Remote command:
CALCulate<n>:MARKer<m>:MAXimum:AUTO on page 993
CALCulate<n>:MARKer<m>:MINimum:AUTO on page 995
Search Limits
The search results can be restricted by limiting the search area or adding search con-
ditions.
Search Limits ( Left / Right ) ← Search Limits
If activated, limit lines are defined and displayed for the search. Only results within the
limited search range are considered.
For details on limit lines for searches, see "Peak search limits" on page 459.

Search Threshold ← Search Limits
Defines an absolute threshold as an additional condition for the peak search. Only
peaks that exceed the threshold are detected.
