CALCulate<Ch/Tr>:MARKer<Mk>:REFerence:X <numeric_value>
Defines the stimulus (in Cartesian diagrams: x-axis) value of the reference marker, which can (but
doesn't have to) be displayed using
CALCulate<Ch/Tr>:MARKer<Mk>:REFerence[:STATe] ON
.
<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.
<numeric_value>
Stimulus value of the reference marker.
Range [def. unit] –9.9E+11 Hz to +9.9E+11 Hz [Hz] (for frequency sweeps)
-999 dBm to +999 dBm [dBm] (for power sweeps)
0 s to 127500 s [s] (for time and CW mode sweeps)
*RST value 0 Hz
SCPI, Command
Types
Device-specific, command or query.
Example:
Suppose that the active setup contains an active trace no. 1 (see
example for CALCulate<Ch>:PARameter:SELect) and 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.
CALCulate<Ch/Tr>:MARKer<Mk>:REFerence:Y?
Returns the response (in Cartesian diagrams: y-axis) value of the reference marker. The reference
marker must be created before using
CALCulate<Ch/Tr>:MARKer<Mk>:REFerence[:STATe] ON
.
<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.
Response Response value of the reference marker.
