"Left"
Determines the next maximum/minimum to the left of the current
peak.
"Absolute"
Determines the next maximum/minimum to either side of the current
peak.
"Right"
Determines the next maximum/minimum to the right of the current
peak.
Remote command:
Chapter 11.8.8.4, "Positioning the Marker"
Exclude LO
If activated, restricts the frequency range for the marker search functions.
"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
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 Modulation Analysis, the unit and value range depend on the selected
result display type.

Chapter 7.9.4.8, "Marker Peak List"
Remote command:
CALCulate<n>:MARKer<m>:PEXCursion
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.
For spectrogram displays, define which frame the peak is to be searched in.
Remote command:
CALCulate<n>:MARKer<m>:MAXimum:AUTO
CALCulate<n>:MARKer<m>:MINimum:AUTO
Search Limits
The search results can be restricted by limiting the search area or adding search con-
ditions.
