Peak Excursion
Defines the minimum level value by which a signal must rise or fall so that it will be
identified 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 more information see chapter 7.4.1.4, "Searching for Signal Peaks", on page 486.
Remote command:
CALCulate<n>:MARKer:PEXCursion on page 934
Auto Max / Min Peak Search
If activated, a maximum or minimum peak search is performed automatically for
marker 1 after each sweep.
For spectrogram displays, define which frame the peak is to be searched in.
For EMI measurements, these functions are not available; use Automatic Peak Search
instead (see chapter 5.13.4.2, "EMI Final Measurement Configuration", on page 302).
Remote command:

CALCulate<n>:MARKer<m>:MINimum:AUTO on page 938
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 486.
Remote command:
CALCulate:MARKer:X:SLIMits[:STATe] on page 935
CALCulate:MARKer:X:SLIMits:LEFT on page 935
CALCulate:MARKer:X:SLIMits:RIGHT on page 935
Search Threshold ← Search Limits
Defines an absolute threshold as an additional condition for the peak search. Only
peaks that exceed the threshold are detected.
Remote command:
CALCulate:THReshold on page 936
Using Zoom Limits ← Search Limits
If activated, the peak search is restricted to the active zoom area defined for a single
zoom (see "Single Zoom" on page 448).
Remote command:
CALCulate:MARKer:X:SLIMits:ZOOM[:STATe] on page 936
