:CALCulate:MARKer[n]:X:SPAN <param>

:CALCulate:MARKer[n]:X:SPAN?

Change the frequency span of the designated span- type

marker pair to position the markers at the desired trace X

values. The value is in the X- axis units (which is usually

query returns the latest marker reading as a span (always

positive).
