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>

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"

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>
