:CURSor:TRACk:SOURce2
Syntax
:CURSor:TRACk:SOURce2 <source>
:CURSor:TRACk:SOURce2?
Description
Sets or queries the track source of Cursor B (X cursor) in the track mode of cursor measurement.
Parameter
Name
Type
Range
Default
<source>
Discrete
{CHANnel1|CHANnel2|CHANnel3|CHANnel4|MATH|NONE}
CHANnel1
Remarks
 Only the currently enabled channel can be selected as the source channel.
 When <source> is set to "NONE", it indicates that Cursor B (X cursor) will not be used.
Return Format
The query returns CHAN1, CHAN2, CHAN3, CHAN4, MATH, or NONE.
:CURSor:TRACk:XDELta?
Syntax
:CURSor:TRACk:XDELta?
Description
Queries the difference (namely △X) between the X value at Cursor A (X cursor) and the X value at Cursor B
(X cursor) in the track mode of cursor measurement. The default unit is s.
Remarks
 For the horizontal position of Cursor A (X cursor), refer to the :CURSor:TRACk:CAX command.
 For the horizontal position of Cursor B (X cursor), refer to the :CURSor:TRACk:CBX command.
Return Format
The query returns the current difference in scientific notation.
:CURSor:TRACk:YDELta?
Syntax
:CURSor:TRACk:YDELta?
Description
Queries the difference (namely △Y) between the Y value at Cursor A (Y cursor) and the Y value at Cursor B
(Y cursor) in the track mode of cursor measurement. The unit is related to the current amplitude unit of the
track source channel of Cursor A (X cursor) and Cursor B (X cursor).
Remarks
 For the vertical position of Cursor A (Y cursor), refer to the :CURSor:TRACk:CAY command.
 For the vertical position of Cursor B (Y cursor), refer to the :CURSor:TRACk:CBY command.
Return Format
The query returns the current difference in scientific notation. When the Y value at Cursor A (Y cursor)
and/or the Y value at Cursor B (Y cursor) exceed(s) the screen range; or when the amplitude units of the
track source channel of current Cursor A (X cursor) and that of current Cursor B (X cursor) are inconsistent,
the query returns 9.9e37.
