Remote command:
Defined by the search function, see
Chapter 12.8.3.6, "Marker search (spectrograms)" ,
on page 1191
Marker Search Area
Defines which frames the search is performed in.
"Visible" Only the visible frames are searched.
"Memory" All frames stored in the memory are searched.
Remote command:
CALCulate<n>:MARKer<m>:SPECtrogram:SARea
on page 1192
CALCulate<n>:DELTamarker<m>:SPECtrogram:SARea

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
on page 1179
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.
Remote command:
CALCulate<n>:MARKer<m>:PEXCursion
on page 1179
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 1183
CALCulate<n>:MARKer<m>:MINimum:AUTO
on page 1185
Search Limits
The search results can be restricted by limiting the search area or adding search con-
ditions.
