Operating Manual 1145.1084.12 – 30 211
It is possible to define up to ten different target values for each trace and assign them to the markers no. 1
to 10. The input fields in the Target Search 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 the trace. 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.
 Value selects the target value to be assigned to the selected marker. The target Value is entered
with the unit of the active trace.
Remote control:
CALCulate<Chn>:MARKer<Mk>:TARget
Search Range...
Opens the Search Range Dialog to confine the target search to a subrange of the sweep.
Bandfilter
Opens a submenu to search for trace segments with a bandpass or bandstop shape and determines
characteristic filter parameters.
Bandfilter search and filter parameters
Bandpass and bandstop regions can be described with the same parameter set:
 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.
