Marker X Axis Position (Remote Command Only)
Sets the marker X position in trace points. It has no effect if the control mode is Off,
but is the SCPI equivalent of entering a value if the control mode is Normal or Delta
except in trace points rather than X-Axis Scale units. The entered value is
immediately translated into the current X-Axis Scale units for setting the value of
the marker.

:CALCulate:TXPower:MARKer[1]|2|...|12:X:POSition <real>
:CALCulate:TXPower:MARKer[1]|2|...|12:X:POSition?
Example
:CALC:TXP:MARK10:X:POS 500
:CALC:TXP:MARK10:X:POS?
Notes The query returns the marker’s absolute X-Axis value in trace points if the control mode is Normal, or
the offset from the marker’s reference marker in trace points if the control mode is Delta. If the marker
is Off the response is not a number
Couplings Max value would be changed by Sweep/Meas Time parameter value
Preset After a preset, all Markers are turned OFF, so Marker X Axis Value query will return a not a number
(NAN)

Marker Y Axis Value (Remote Command Only)
Returns the marker Y-Axis value in the current marker Y-Axis unit.
The “result” of a marker is the value that is displayed on the second line of the
Marker Result block. To properly interpret the returned value, the remote
programmer must also know what the instrument’s Y-Axis Unit is set to as described
below.
A marker can have up to two results, only one of which is displayed or returned on a
query, as follows:
Absolute
result
Every marker has an absolute result and it is simply:
–
For Normal and Delta markers, the Y Axis value of the trace point the marker is
currently on
–
The absolute result is displayed in the result block or returned on a query unless
the marker control mode is Delta
Relative
result
If a marker’s control mode is Delta, the relative result is displayed in the result block
or returned on a query. This is the ratio of the Absolute Result of a delta marker to the
Absolute Result of its reference marker. The ratio is expressed in dB
