Span Markers Center Frequency X Position
:CALCulate:MARKer[1]|2|3|4:X:POSition:CENTer <param>
:CALCulate:MARKer[1]|2|3|4:X:POSition:CENTer?
Position the center frequency, of the designated span-type marker pair,
at the specified trace X position. A trace is composed of 401 points (X
positions.) Use :CALCulate:MARKer:MODE SPAN to select span
markers.
The query returns the current X-position center frequency of the
designated markers.
Range: 0 to 400

Span Markers Span X Position
:CALCulate:MARKer[1]|2|3|4:X:POSition:SPAN <param>
:CALCulate:MARKer[1]|2|3|4:X:POSition:SPAN?
Change the frequency span, of the designated span-type marker pair, to
position the markers at the desired trace X positions. A trace is
composed of 401 points (X positions.) Use CALCulate:MARKer:MODE
SPAN to select span markers.
The query returns the current X-position frequency span of the
designated markers.
Range: 0 to 400
Default Unit: X-axis units (Hz or seconds)

Band Markers Start Frequency X Position
:CALCulate:MARKer[1]|2|3|4:X:POSition:STARt <param>
:CALCulate:MARKer[1]|2|3|4:X:POSition:STARt?
Position the left-most marker, the start (reference) frequency of the
designated band-type marker pair, at the specified trace X position. A
trace is composed of 401 points (X positions.) Use
:CALCulate:MARKer:MODE BAND to select band markers.
The query returns the current X-position start/reference frequency of
the designated marker.
Range: 0 to 400
Default Unit: X-axis units (Hz or seconds)
