CALCulate<Chn>:MARKer<Mk>:REFerence:X
<StimulusValue>[, <Seg>[,
<MeasPoint>]]
In NORMal or FIXed marker mode (see
CALCulate<Chn>:MARKer<Mk>:TYPE
) this
command sets or gets the stimulus value of the reference marker. In ARBitrary mode
this is only true if the X axis represents the stimulus. For all other trace formats (see
) it sets or gets the X position of the reference marker,
which is decoupled from the marker stimulus in this case.
Suffix:
<Chn>
.
Channel number used to identify the active trace
<Mk>
This numeric suffix is ignored and may be set to any value.
Parameters:
<StimulusValue>
If the marker mode of the related marker is ARBitrary and the
trace format is complex (Polar, Smith, inverted Smith), this is the
real part Re(z
M
) of the marker value z
M
. In any other case, it is
the marker's stimulus value.
If the marker mode is ARBitrary and the trace format is complex,
the value range is -1 to +1. Otherwise -9.9E+11 Hz to +9.9E+11
Hz for frequency sweeps, -999 dBm to +999 dBm for power
sweeps, 0 s to 127500 s for time sweeps and 1 to 100001 for
CW mode.
Setting parameters:
<Seg>
For a segmented frequency sweep with overlapping segments,
you can assign the reference marker to a particular segment.
If specified, the <Seg> number must be valid and the <Stimulus-
Value> must be inside the segment.
<Point>
For a segmented frequency sweep with overlapping segments
or with segments that have multiple sweep points at the same
frequency, you can assign the reference marker to a particular
segment <Seg> and sweep point <Point>.
If specified, the <Seg> and <Point> numbers must be valid and
the <StimulusValue> must be inside the segment.
Example:
Suppose that the active recall set contains an active trace no. 1
and that the sweep range for a frequency sweep starts at 1 GHz.
CALC:MARK:REF ON
Create the reference marker and display it in the center of the
sweep range.
CALC:MARK:REF:X 1GHz
Set the reference marker to the beginning of the sweep range.
CALC:MARK:REF:Y?
Query the measurement value at the reference marker position.
Manual operation:
See
"Mkr <i> Stimulus / Ref Mkr Stimulus"
CALCulate<Chn>:MARKer<Mk>:REFerence:Y
<RefResponseValue>
Sets or gets the (response) value of the related reference marker.
