Defines the output format for the (complex) value of marker <Mk> on trace no. <Chn>.
Note:
The formats of the markers assigned to a trace are independent of each other and of the trace
format settings; see
CALCulate<Chn>:FORMat
.
<Chn>
Channel number used to identify the active trace.
<Mk>
Marker number in the range 1 to 10.
Parameters
See list of parameters below.
*RST value
DEFault
SCPI, Command
Types
Device-specific, command or query
Example:
Suppose that the active setup contains an active trace no. 1.
CALC:MARK ON; CALC:MARK:FORM?
Create marker 1, assign it to the trace no. 1 and query its format. The analyzer
returns the format of the active trace.
Assume that the marker result is given by the complex quantity z = x + jy. The meaning of the parameters
is as follows:
DEFault
The format of the trace no. <Chn> (MLOG after *RST); see
CALCulate<Chn>:FORMat
.
