The commands in the MARKer subsystem specify and query the settings of
the time markers (X axis) and current measurement unit markers (volts,
amps, and watts for the Y axis). You typically set the Y- axis measurement
units using the :CHANnel:UNITs command.

Guidelines for Using Queries in Marker Modes
In Track Waveforms mode, use :MARKer:CURSor? to track the position of the waveform. In
Manual Markers and Track Measurements Markers modes, use other queries, such as the
X1Position? and X2Position?, 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.
