210 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
11 Marker
The difference between Span Pair and Delta modes is that in Span Pair mode the reference
marker stays on the trace and you can adjust its trace point.
Once positioned, the markers stay on the trace points on which they have been placed.
Changing the frequency or time of the N8201A does not change the trace point of the
markers, that is, they stay at the same horizontal position on the display.
You cannot move the markers off the screen. If you adjust either center or span to a value
that would cause one of the markers to move off screen, the marker will be placed at the
right or left side of the display, on the trace. Changing the Center marker changes the center
point of the two markers. This function is useful in functions such as Marker Fctn > Band
Power.

:CALCulate:MARKer[1]|2|3|4:X:POSition:CENTer <param>
Sets the mid point of the markers to a specific trace point.
:CALCulate:MARKer[1]|2|3|4:X:POSition:CENTer?
Returns the midpoint trace point.
:CALCulate:MARKer[1]|2|3|4:X:POSition:SPAN <param>
Sets the spacing between the markers to a specified number of trace points.
:CALCulate:MARKer[1]|2|3|4:X:POSition:SPAN?
