RIGOL Chapter 2 Command System
2-76 DS4000E Programming Guide
 When Y is selected as the track axis, you can use the :CURSor:TRACk:CAX and :CURSor:TRACk:CBX
commands to adjust the horizontal position of X cursor. Then, Y cursor will automatically track the
vertical amplitude of the waveform of the corresponding measurement source at X cursor.
Return Format
The query returns X or Y.
:CURSor:TRACk:AYValue?
Syntax
:CURSor:TRACk:AYValue?
Description
Queries the Y value at Cursor A (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).
Remarks
 In the track mode, when Cursor A (X cursor) is adjusted horizontally, Cursor A (Y cursor) will
automatically track the vertical amplitude of the waveform of the corresponding track source channel
at Cursor A (X cursor).
 For the vertical position of Cursor A (Y cursor), refer to the :CURSor:TRACk:CAY command.
Return Format
The query returns the Y value in scientific notation. When the Y value at Cursor A (Y cursor) exceeds the
screen range, the query returns 9.9e37.
:CURSor:TRACk:BXValue?
Syntax
:CURSor:TRACk:BXValue?
Description
Queries the X value at Cursor B (X cursor) in the track mode of cursor measurement. The default unit is s.
Remarks
 In the track mode, when Cursor B (Y cursor) is adjusted vertically, Cursor B (X cursor) will
automatically track the time or frequency of the waveform of the corresponding track source channel
at Cursor B (Y cursor).
 For the horizontal position of Cursor B (X cursor), refer to the :CURSor:TRACk:CBX command.
Return Format
The query returns the X value in scientific notation.
:CURSor:TRACk:BYValue?
Syntax
:CURSor:TRACk:BYValue?
Description
Queries 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 B (X cursor).
