Example: Suppose that the active recall set contains an active trace no. 1.
CALC:MARK1 ON; MARK2 ON
Create markers 1 and 2 and assign them to the trace no. 1.
CALC:MARK:AOFF
Remove both markers.
Usage: Event
Manual operation: See "All Off" on page 392
CALCulate<Chn>:MARKer<Mk>:BWIDth <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).
The response to the query CALCulate<Chn>:MARKer<Mk>:BWIDth? contains the
following bandfilter search results:
●
<Bandwidth> – bandwidth of the bandpass/bandstop region.
●
<Center> – stimulus frequency at the center of the bandpass/bandstop region (the
stimulus value of marker M4).
●
<QualityFactor (3 dB)> – quality factor, i.e. the ratio between the center frequency
and the 3-dB bandwidth.
●
<Loss> – loss at the center of the bandpass/bandstop region (the response value
of marker M4 at the time of the bandfilter search).
●
<LowerEdge> – lower band edge.
●
<UpperEdge> – upper band edge.
Tip: To obtain the <Quality Factor (BW)> result from the bandfilter info field, calculate
the ratio <Center> / <Bandwidth>.
Suffix:
<Chn>
.
Channel number used to identify the active trace
<Mk> This numeric suffix is ignored and may be set to any value
because the bandfilter search functions always use markers M1
to M4.
Parameters:
<Bandwidth> Difference between the band edges and the center response
value of a bandfilter peak; must be negative for a bandpass
search and positive for a bandstop search.
Range: For bandpass: -100.00 dB to -0.01 dB; for band-
stop: +0.01 dB to +100.00 dB
Increment: 0.03 dB
*RST: -3 dB
Default unit: dB
