CURSor:DDT?
Examples
CURSOR:DDT? might return :CU RSOR:DDT -166.6670 indicating that the
cursor dV/d
t read out is -166.6670
CURSor:FUNCtion
This command selects the cursor mode. In Waveform mode, the cursors are
attached to the selected waveform; in Screen mode, cursors are attached to the
display area .

Cursor
Syntax
CURSor:FUNCtion {SCREEN|WAVEform|OFF}
CURSor:FUNCtion?
Related Commands
CURSor:SOUrce,
CURSor:MODe
Arguments
SCREEN specifies to display both horizontal and vertical bar cursors, which
measure the selected waveform in horizontal and vertical units. Use these cursors
to measure anywhere in the waveform display area.
WAVEform specifies to display the paired cursors in YT display format for
measuring waveform amplitude and time. In XY and XYZ format, these cursors
indicate the amplitude positions of an XY pair (Ch1 vs Ch2 voltage, where Ch1is
the X axis and Ch2 is the Y axis) relative to the trigger.
OFF removes the cursors from the display.
Examples
CURSOR:FUNCTION WAVEFORM selects the paired cursors for measuring waveform
amplitude and time.
CURSOR:FUNCTION? might return :CUR Sor:FUNCtion SCREEN indicating that
the screen cursors are currently selected.
CURSor:HBArs? (Query Only)
Returns the current settings for the horizontal bar cursors.

<NR3> is a floati
ng point number that specifies the cursor position relative to
ground.
Examples
CURSOR:HBARS:POSITION1 25.0E-3 positions Cursor 1 of the horizontal
cursors at 25 mV.
CURSOR:HBARS:POSITION2? might return :CURSOR:HBARS:POSITION2

Arguments
BASE selects the vertical units for the selected waveform.
PERcent selects ratio cursors.
Examples
CURSOR:HBARS:UNITS might return :C UR
SOR:HBARS:UNITS BASE
indicating
that the units for the horizontal bar cursors are base.
CURSor:HBArs:USE (No Query Form)
This command specifies the horizontal bar cursor measurement scale. This
command is only applicable when the ratio cursors are turned on.
