Opens a dialog to define the peak type to be searched for.
It is possible to select the peak type up to ten times for each trace and assign the selection to the markers no. 1 to 10.
The radio buttons in the Peak Type panel offer the following alternative peak types:
Opens the Search Range Dialog to confine the minimum/maximum search to a subrange of the sweep.
Defines search ranges for the maximum/minimum or target search.
It is possible to define up to ten different search ranges for each setup and assign them to the markers no. 1 to 10. The input fields in the Search Range dialog are used to select the markers and define the associated search ranges:
In contrast to the marker properties defined in the Marker and Search menus, the ten search ranges are valid for the entire setup. This means that, once defined, each of them can be assigned to any marker in the setup, irrespective of the trace and channel that the marker belongs to.
The default search range of each new marker is Full Span. The analyzer provides the greatest flexibility in defining search ranges. In particular, two search ranges may overlap or even be identical. The search is confined to the part of the search range that belongs to the sweep range.
The following example shows how search ranges can be used to search a trace for several local maxima.

Causes the active minimum/maximum or target search of the active marker to be repeated after each sweep: When tracking mode is active the marker typically changes its horizontal and its vertical position as the measurement goes on.
The tracking mode is available for all search modes, i.e. for minimum/maximum search, target search and bandfilter search. The Marker Tracking function in the Search submenu is valid for an active minimum/maximum and target search; bandfilter tracking can be activated separately. Tracking is marker-specific but can be switched on for several markers simultaneously.
Switching between Max Search and Min Search does not affect the tracking mode.Tracking is switched off though when one of the following actions is performed:
Redefinition of the active marker position by means of the functions in the Marker menu or drag-and-drop of the active marker symbol.
Change of the active marker's search mode, e.g. from a minimum/maximum search to a target search.
Tracking is a toggle function: Selecting the function repeatedly switches the tracking mode on and off.
