Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<HorizontalPos> LEFT | MID | RIGHt
Horizontal position
<VerticalPos> TOP | MID | BOTTom
Vertical position
Example: See
CALCulate<Chn>:MARKer<Mk>:BWIDth
Manual operation: See "Bandpass Ref to Max" on page 546
CALCulate<Chn>:MARKer<Mk>:AOFF
Removes all markers from all traces of the active recall set. The removed markers
remember their properties (stimulus value, format, delta mode, number) when they are
restored (
CALCulate<Chn>:MARKer<Mk>[:STATe] ON
). The marker properties are
definitely lost if the associated trace is deleted.
Suffix:
<Chn>
.
Channel number used to identify the active trace. If unspecified
the numeric suffix is set to 1.
<Mk> Marker number in the range 1 to 10. This numeric suffix is
ignored and may be set to any value.
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 533
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.
