"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:

Search Mode (Spectrograms)
Spectrograms show not only the current sweep results, but also the sweep history.
Thus, when searching for peaks, you must define the search settings within a single
time frame (x-direction) and within several time frames (y-direction).
This setting is only available for spectrogram displays.
Search Mode for Next Peak in X Direction ← Search Mode (Spectrograms)
Selects the search mode for the next peak search within the currently selected frame.
"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.

Search Mode for Next Peak in Y Direction ← Search Mode (Spectrograms)
Selects the search mode for the next peak search within all frames at the current
marker position.
"Up"
Determines the next maximum/minimum above the current peak (in
more recent frames).
"Absolute"
Determines the next maximum/minimum above or below the current
peak (in all frames).
"Down"
Determines the next maximum/minimum below the current peak (in
older frames).
