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:
• Marker Selects one of the ten markers that can be assigned to a trace in the current setup. If a
selected marker does not exist, it is created as soon as On is checked. A created marker is
displayed in the center of the search range.
• Search Range Selects the search range to be assigned to the selected marker. Full Span
means that the search range is equal to the sweep range. Besides, it is possible to store up to
10 customized search ranges.
• Start defines the beginning of the search range. Start must be smaller than the Stop value,
otherwise the search will not be initiated.
• Stop defines the end of the search range. Stop must be larger than the Start value, otherwise
the search will not be initiated.
• Range Limit Lines On displays two vertical lines indicating the Start and the Stop value of the
current search range in the diagram area. This function is enabled as soon as one of the search
ranges 1 to 10 is selected.
Search range properties
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.
