Bandstop Ref to Max
Activates the search for a bandstop region on the active trace and activates Tracking.
A bandstop region is the lowest peak (local minimum) in the search range, whose level
is at least <Bandwidth> below the maximum (passband value).
If "Bandstop Ref to Max" is selected, the analyzer uses (or creates) the four markers
"M1" to "M4" to locate the bandstop region.
●
"M1" indicates the minimum of the peak ("Min").
●
"M2" indicates the "Lower Edge" of the bandstop, i.e. the point on the left edge of
the peak where the trace value is equal to the maximum in the search range (pass-
band value) minus the specified Bandwidth.
●
"M3" indicates the "Upper Edge" of the bandstop, i.e. the point on the right edge of
the peak where the trace value is equal to the maximum in the search range (pass-
band value) minus the specified "Bandwidth".
●
"M4" indicates the center of the peak. Depending on a system setting, the center is
either calculated as the geometric or the arithmetic mean of the "Lower Edge" and
"Upper Edge" positions (see "Geometric Calculation of Bandfilter Center"
on page 866).
The search results are displayed in the movable "Bandfilter" info field.
Remote command:
CALCulate<Chn>:MARKer<Mk>:FUNCtion:BWIDth:MODE BSTop
CALCulate<Chn>:MARKer<Mk>:FUNCtion:EXECute BFILter
Result Off
Hides the movable info field with the results of a bandpass or a bandstop search and
disables Tracking. The info field is displayed again (and tracking re-enabled) when a
new "Bandfilter" search is performed.
Remote command:
CALCulate<Chn>:MARKer:SEARch:BFILter:RESult[:STATe]
Search (Bandpass or Bandstop) / Search Mode
Enables a bandpass or bandstop search (left/right icon) for an arbitrary search mode.
The search modes have the following effect:
●
"Ref to Max": The bandpass (bandstop) is the tallest (lowest peak) in the search
range. For a detailed description, refer to "Bandpass Ref to Max" on page 516 and
"Bandstop Ref to Max" on page 517.
