• Mkr 1 indicates the maximum of the peak (Max).
• Mkr 2 indicates the point on the left edge of the peak where the trace value is equal to the
maximum minus x dB Bandwidth (Lower Band Edge, LBE).
• Mkr 3 indicates the point on the right edge of the peak where the trace value is equal to the
maximum minus x dB Bandwidth (Upper Band Edge, UBE).
• Mkr 4 indicates the center of the peak, calculated as the geometric mean value of the LBE and
UBE positions: f
Center
= sqrt (f
LBE
* f
UBE
).
The band filter search results are displayed in the bandfilter info field.
To search for a bandpass region in the vicinity of the active marker, use Bandpass Search Ref to
Marker. Use Bandfilter Tracking to select other search modes.
Remote control:
CALCulate<Chn>:MARKer<Mk>:FUNCtion:BWIDth:MODE BPASs
CALCulate<Chn>:MARKer<Mk>:FUNCtion:EXECute BFILter
Bandpass Search Ref to Marker
Activates the search for a bandpass region on the active trace and activates bandfilter Tracking, starting at
the position of the active marker. A bandpass region is the closest peak in the search range with a
minimum excursion specified by means of the x dB Bandwidth parameter.
In contrast to a Bandpass Search, the Bandpass Search Ref to Marker does not change the position of
the active markers. The band filter search results are displayed in the bandfilter info field.
To search for a bandstop region in the vicinity of the active marker, use Bandfilter Tracking –
Bandstop Search Ref to Marker. Use Bandfilter Tracking to select other search modes.

Bandstop Search Ref to Max
Activates the search for a bandstop region on the active trace and activates bandfilter Tracking. A
bandstop region is the lowest peak (local minimum) in the search range, provided that its level is at least
<x dB Bandwidth> below the maximum (passband value).
