For the horizontal position of Cursor B (X cursor), refer to the :CURSor:TRACk:CBX command.
Return Format
The query returns the reciprocal of the current difference in scientific notation. When the difference is 0 s,
the query returns 9.9e37.
:CURSor:TRACk:SEQuence
Syntax
:CURSor:TRACk:SEQuence <seq>
:CURSor:TRACk:SEQuence?
Description
Sets or queries the track type of X cursor when X is selected as the track axis (refer to
the :CURSor:TRACk:AXIS command).
Parameter

<seq>
Discrete {FIRSt|LAST}
FIRSt
Remarks
FIRSt: When you adjust the vertical position of Y cursor, if the waveforms of corresponding
measurement channels have formed multiple crossing points along the cursor, then X cursor will be
automatically located at the crossing point of the most left side of the screen.
LAST: When you adjust the vertical position of Y cursor, if the waveforms of corresponding
measurement channels have formed multiple crossing points along the cursor, then X cursor will be
automatically located at the crossing point of the most right side of the screen.
Return Format
The query return FIRS or LAST.
:CURSor:TRACk:SOURce1
Syntax
:CURSor:TRACk:SOURce1 <source>
