Create markers 1 and 2 and assign them to the trace no. 1.
CALC:MARK:AOFF
Remove both markers.
CALCulate<Chn>:MARKer<Mk>:BWIDth <x_dB_Bandwidth>
Sets the bandfilter level for a bandfilter search or returns the results. The command is only available after
a bandfilter search has been executed (CALCulate<Chn>:MARKer<Mk>:FUNCtion:EXECute
BFILter; see example below).
Channel number used to identify the active trace.
Marker number in the range 1 to 10. This numeric suffix is ignored and may
be set to any value because the bandfilter search functions always use
markers M 1 to M 4.
x dB Bandwidth parameter. The x dB Bandwidth is the difference between
the band edges and the center response value of a bandfilter peak; it must
be negative for a bandpass search and positive for a bandstop search.
For bandpass: –100.00 dB to –0.01 dB, the increment (UP/DOWN) is 0.3 dB.
[dB]
For bandstop: +0.01 dB to +100.00 dB, the increment (UP/DOWN) is 0.3 dB.
[dB]
Search result in the format <Bandwidth>, <Center_Stimulus>, <Q>, <Loss>,
<LBE>, <UBE> where:
n-dB bandwidth of the bandpass/bandstop region, where n is the selected x
dB Bandwidth (setting command CALCulate<Chn>:MARKer<Mk>:BWIDth
<x dB Bandwidth>).
Stimulus frequency at the center of the bandpass/bandstop region (the
stimulus value of marker no. 4).
Quality factor, i.e. the ratio between the center frequency and the 3-dB
bandwidth
Loss at the center of the bandpass/bandstop region (the response value of
marker no. 4 at the time of the bandfilter search).
Depending on the measurement parameter. [units depending on the sweep
type and the marker format; see CALCulate<Chn>:MARKer<Mk>:FORMat]
Device-specific, query only.
CALC:MARK:FUNC:BWID:MODE BST
Select a bandstop filter search.
CALC:MARK:FUNC:BWID:GMC OFF
Use the arithmetic mean value of lower and upper band edge to calculate the
