Bandwidth
Specifies the minimum excursion of the bandpass and bandstop peaks.
●
A bandpass peak must fall off on both sides by the specified <Bandwidth> value to
be considered a valid peak.
●
A bandstop peak must be <Bandwidth> below the maximum level in the search
range (bandpass value) to be considered a valid peak.
Remote command:
CALCulate<Chn>:MARKer<Mk>:BWIDth
Bandpass Ref to Max
Activates the search for a bandpass region on the active trace and activates Tracking.
The located bandpass region is the tallest peak in the search range with a minimum
excursion as specified by the "Bandwidth" parameter.
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
