:CALCulate:DDEMod:MARKer<n>:X
Syntax
:CALCulate:DDEMod:MARKer<n>:X <real>
:CALCulate:DDEMod:MARKer<n>:X?
Description

Remarks
<real> can be any value within the available range of the current X axis. When frequency-domain data
source is selected, the X value represents the frequency; when time data source is selected, the X value
represents the time.
If the marker mode of the specified marker is Position or Fixed, this command sets the X value of the
marker.
If the specified marker mode is Delta, this command sets the X value of the delta marker relative to the
reference marker.
When "Fixed" is selected for the marker mode and "Constellation" is selected for the trace format, Marker X
is used to determine the data points.
Return Format
The query returns the X-axis value of the marker in scientific notation.
Example
The following command sets the X-axis value of Marker 1 to 150 MHz.
:CALCulate:DDEMod:MARKer1:X 150000000
The following query returns 1.50008.
:CALCulate:DDEMod:MARKer1:X?
:CALCulate:DDEMod:MARKer<n>:Y:IMAGinary
Syntax
:CALCulate:DDEMod:MARKer<n>:Y:IMAGinary <real>
:CALCulate:DDEMod:MARKer<n>:Y:IMAGinary?
Description
Sets the selected marker's quadrature component (imaginary) of the Y value.
Queries the selected marker's quadrature component (imaginary) of the Y value.

format, the command is valid.
