CALCulate<Ch/Tr>:MARKer<Mk>:AOFF
Removes all markers from all traces of the active setup. The removed markers remember their
properties (stimulus value, format, delta mode, number) when they are restored
(CALC<Ch/Tr>:MARK<Mk> ON). The marker properties are definitely lost if the associated trace is
deleted.
<Ch/Tr> 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.

Command
Types
Device-specific, no query.
Example:
Suppose that the active setup contains an active trace no. 1
(see example for CALCulate<Ch>:PARameter:SELect).
CALC:MARK1 ON; MARK2 ON
Create markers 1 and 2 and assign them to the trace no. 1.
CALC:MARK:AOFF
Remove both markers.
CALCulate<Ch/Tr>:MARKer<Mk>:BWIDth <x_dB_Bandwidth>
Sets the bandfilter level for a bandfilter search or returns the results. The query form is only available
after a bandfilter search has been executed
(
CALCulate<Ch/Tr>:MARKer<Mk>:FUNCtion:EXECute BFILter
; see example below).
<Ch/Tr> 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 Mkr1 to Mkr4.
<x_dB_Bandwidth> 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.
Range [def. unit] 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]
*RST value –3 dB
Response for
query: Search result in the format <Bandwidth>, <Center_Stimulus>,
<Q>, <Loss>, <LBE>, <UBE> where:
<Bandwidth>
n-dB bandwidth of the bandpass/bandstop region, where n is the
selected
x dB Bandwidth (setting command
CALCulate<Ch/Tr>:MARKer<Mk>:BWIDth <x dB
Bandwidth>
).
