CURSor?
Query :MARKer:CURSor? {DELTa | STARt | STOP}
The :MARKer:CURSor? query returns the time and current measurement unit
values of the specified marker (if markers are in Track Waveforms mode) as an
ordered pair of time and measurement unit values.
• If DELTA is specified, the value of delta Y and delta X are returned.
• If START is specified, marker A’s x-to-y positions are returned.
• If STOP is specified, marker B’s x-to-y positions are returned.
Returned Format
[:MARKer:CURSor] {DELTa | STARt | STOP}
{<Ax, Ay> | <Bx, By> | <deltaX, deltaY>}<NL>
Example This example returns the current position of the X cursor and measurement
unit marker 1 to the string variable, Position$. The program then prints the
contents of the variable to the computer's screen.

C A U T I O N The :MARKer:CURSor? query may change marker mode and results.
In Track Waveforms mode, use :MARKer:CURSor? to track the position of the
waveform. In Manual Markers and Track Measurements Markers modes, use
other marker queries, such as the TSTArt? and TSTOp?, and VSTArt? and
VSTOp? queries.
If you use :MARKer:CURSor? when the oscilloscope is in either Manual
Markers or Track Measurements Markers modes, it will put the oscilloscope
in Track Waveforms mode, regardless of the mode previously selected. In
addition, measurement results may not be what you expected.
