If "Bandpass Ref to Max" is selected, the analyzer uses (or creates) the four markers
"M1" to "M4" to locate the
bandpass region
.
●
"M1" indicates the maximum of the peak ("Max").
●
"M2" indicates the point on the left edge of the peak where the trace value is equal
to the maximum minus the bandwidth factor ("Lower Edge").
●
"M3" indicates the point on the right edge of the peak where the trace value is
equal to the maximum minus the bandwidth factor ("Upper Edge").
●
"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" frequencies (see
"Geometric Calculation of Bandfilter Center"
The search results are displayed in the movable "Bandfilter" info field.
Remote command:

Bandpass Ref to Mkr
Activates the search for a bandpass region on the active trace and activates
starting at the position of the active marker. A bandpass region is the closest peak in
the evaluation range that has a minimum excursion as specified by the "Bandwidth"
parameter.
In contrast to a "Bandpass Ref to Max", the "Bandpass Ref to Mkr" does not change
the position of the active markers. The search results are displayed in the movable
"Bandfilter" info field.
Remote command:
CALCulate<Chn>:MARKer<Mk>:FUNCtion:BWIDth:MODE BPRMarker

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