:CALC:PVTime:MARK:X?
Notes Marker X does not go outside the bounds of the data. If you attempt to set it to a value outside the
bounds, it is clipped at the closest limit and error -222 Data Out of Range is generated.
If suffix is sent, it must match the X units for the trace the marker is on. Otherwise, error -138, "Suffix
not allowed" is generated.
If you try to read or set the position of a Delta marker, remember that the position is in relative units.
Couplings See "Coupling of Delta and Reference markers " on page 1380.
Preset None until marker is turned on.
State Saved Yes
Min Depends on trace data
Max Depends on trace data
SCPI only X position commands
Via SCPI, the marker position can also be set or queried in trace points. In this case,
the position setting or reading is absolute regardless of control mode.
NOTE
The entered value in Trace Points is immediately translated into the current
domain units for setting the value of the marker. The marker’s value in domain
units, NOT trace points, is preserved if a change is made to the X Axis scale
settings. Thus, if you use this command to place a marker on point 500, which
happens at that time to correspond to 13 GHz, and then you change the Start
Frequency so that point 500 is no longer 13 GHz, the marker stays at 13 GHz,
NOT at point 500.
If the trace the marker is on a 2-dimensional domain, then the points are numbered
in the following way:
Starting at the minimum X and Z position, this point is numbered 0. Each time you
increment the point number, increment the X value to the next available value.
When X reaches the maximum X position, then reset X to the minimum and
increment the Z value. Then continue incrementing the X position in the same
manner as before.
Note that for symbol tables, which have no axes, incrementing the X position in
points moves the marker consecutively through all table entries.

:CALCulate:PVTime:MARKer[1]|2|...|12[:X]:POSition <real>
:CALCulate:PVTime:MARKer[1]|2|...|12[:X]:POSition?
Example
:CALC:PVTime:MARK:POS 25
:CALC:PVTime:MARK:POS?
Notes When a marker mode is changed from off to any other mode, the X position is set to mid-screen.
