Search Mode for Next Peak
Selects the search mode for the next peak search.
"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:

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.

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.
