CALCulate Subsystem
:CALCulate:MARKer[1]|2|3|4:X:STARt?
Position the start (reference) frequency of the designated band-type
marker pair, at the specified trace X value. The value is in the X-axis
units (which is often frequency or time). Use
:CALCulate:MARKer:MODE BAND to select band markers.
The query returns the current X-value start/reference frequency of the
designated marker.
Default Unit: Matches the units of the trace on which the markers
are positioned

:CALCulate:MARKer[1]|2|3|4:X:STOP <param>
:CALCulate:MARKer[1]|2|3|4:X:STOP?
Position the stop frequency of the designated band-type marker pair, at
the specified trace X value. The value is in the X-axis units (which is
often frequency or time). Use :CALCulate:MARKer:MODE BAND to
select band markers.
The query returns the current X-value stop frequency of the designated
marker.
Default Unit: Matches the units of the trace on which the markers
are positioned

Marker Read Y Value
:CALCulate:MARKer[1]|2|3|4:Y?
Read the current Y value for the designated marker or delta on its
assigned trace. The value is in the Y-axis units for the current trace
(which is often dBm).
Default Unit: Matches the units of the trace on which the marker is
positioned
Remarks: This command can be used to read the results of
marker functions such as band power and noise that
are displayed in the marker value field on the analyzer.
