CALCulate<Chn>:MARKer<Mk>:FUNCtion:BWIDth <x dB Bandwidth>
[Deprecated command]
Defines the bandfilter level, i.e. the minimum excursion for the bandpass and bandstop peaks.
Use CALCulate<Chn>:MARKer<Mk>:BWIDth to set the x dB Bandwidth and query the results of a
bandfilter search. Note the sign convention for input values.
<Chn>
Channel number used to identify the active trace
<Mk>
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>
x dB Bandwidth parameter
Range [def. unit]
0.01 dB to 100.00 dB, the increment (UP. DOWN) is 0.3 dB. [dB]
*RST value
3 dB.

Types
Device-specific, command or query.
Example:
See CALCulate<Chn>:MARKer<Mk>:BWIDth.
CALCulate<Chn>:MARKer<Mk>:FUNCtion:BWIDth:GMCenter <Boolean>
Specifies how the center frequency of a bandfilter search is calculated.
<Chn>
Channel number used to identify the active trace
<Mk>
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.
<Boolean>
ON – use geometric mean of lower and upper band edge
OFF – use arithmetic mean value
*RST value
n/a (*RST does not affect the calculation rule; the factory setting is ON/geometric
mean)
