9.3.3.2 Marker Search Settings for Spectrograms
Access : "Overview" > "Analysis" > "Markers" > "Search"
or : [MKR TO] > "Search Config"
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).
These settings are only available for spectrogram displays.
