x dB Bandwidth
Opens the numeric entry bar for the minimum excursion of the bandpass and bandstop peaks.
 A bandpass peak must fall off on both sides by the specified x dB Bandwidth to be considered a
valid peak.
 A bandstop peak must be x dB Bandwidth below the maximum level in the search range
(bandpass value) to be considered a valid peak.

Search Range...
Opens the Search Range Dialog to confine the bandfilter search to a subrange of the sweep.
It is possible to define and store up to ten different search ranges for each trace. The bandfilter search is
performed using the markers M 1, ..., M 4, irrespective of the selected search range.
 Search Range Selects a search range for the bandfilter search. 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 bandfilter 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
The ten search ranges are valid for the entire setup. 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 any new marker is Full Span. The analyzer provides 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 bandpass
regions.
