•
A bandpass region contains a local maximum around which the magnitude of the trace falls off
by more than a specified
x dB Bandwidth .
•
A bandstop region contains a local minimum around which the magnitude of the trace increases
by more than a specified
x dB Bandwidth .
The analyzer locates bandpass and bandstop regions and determines their position (Center frequency)
and shape (Bandwidth, LBE, UBE , Quality factor Q ; see Show Results). For a meaningful definition of
the x dB Bandwidth criterion, the trace format must be dB Mag.
•
Bandpass Search Ref to Max activates the search for a bandpass region in the active trace,
starting at the absolute maximum of the active trace within the search range.
•
Bandstop Search activates the search for a bandstop region in the active trace, starting at the
absolute minimum of the active trace within the search range.
•
Bandfilter Tracking causes the bandfilter search to be repeated after each sweep.
•
x dB Bandwidth... sets the level defining the filter bandwidth.
•
Search Range... confines the search to a subrange of the sweep.
•
Search Result Off hides the display of the bandfilter parameters in the diagram area.
