Commands Listed in Alphabetical Order
Arguments
<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
-64.0000E-03
indicating that Cursor 2 of the horizontal bar cursors is at -64 mV.
CURSor:HBArs:UNIts
This command specifies the units for the horizontal bar cursors.

Cursor
Syntax
CURSor:HBArs:UNIts {BASE|PERcent}
CURSor:HBArs:UNIts?
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.

Syntax
CURSor:HBArs:USE {CURrent|HALFgrat}
Related Commands
CURSor:HBArs:UNIts
Arguments
CURrent sets the H Bar measurement scale so that 0% is the current position of the
lowest H Bar cursor and 100% is the current position of the highest H Bar cursor.

HALFgrat sets H
Bar measurement scale so that half the screen major divisions
(five on the MSO/DPO4000B and MDO4000/B/C, four on the MDO3000) is
100%, where 0% is -2.5 divisions and 100% is +2.5 divisions from the center
horizontal graticule.
Examples
CURSOR:HBARS:USE HALFGRAT sets the H Bar measurement scale so that
five screen major divisions equals 100%.
CURSor:MODe
This command specifies whether the two cursors move linked together in unison
or separately. This command is equivalent to setting Linked to On or Off in the
Cursor menu.
Group
Cursor
Syntax
CURSor:MODe {TRACk|IND ependent}
CURSor:MODe?
Arguments
TRACk ties the navigational functionality of the two cursors together. For cursor 1
adjustments, this ties the movement of the two cursors together; however, cursor 2
continues to move independently of cursor 1. This mode only applies when the
DISplay:XY:WITHYT is set to
OFF.
INDependent allows independent adjustment of the two cursors.
Examples
CURSOR:MODE TRACK specifies that the cursor positions move in unison.
CURSOR:MODE? might return :CURSOR:MODE TRACK indicating that the two
cursorsmoveinunison.
CURSor:SOUrce
This command specifies the cursor source waveform, which can be one of channels
1-4, reference waveforms 1-4, math waveform, bus 1-4 (1-3 for the MDO4000C
and 1-2 for the MDO3000), digital channels 0-15 (MSO/MDO4000/B models
only as well as MDO3000 and MDO400C models with option MDO3MSO or
MDO4MSO installed), the RF time domain traces (MDO4000/B/C models), or
AUTO. When the cursor source is set to AUTO, cursor readouts apply to the
currently selected waveform.

SELect:CONTROl,
CURSor:MODe,
CURSor:FUNCtion
Arguments
CH1-4 – specifies one of the analog waveforms as the cursor source.
REF1-4 – specifies one of the reference waveforms as the cursor source.
MATH – specifies the cursor source as the math waveform.
BUS1-4 – specifies the cursor source as one of the bus waveforms.
D0–D15 – specifies the cursor source as one of the digital waveforms.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
RF_AMPlitude|RF_FREQuency|RF_PHASe – specifies the cursor source as one
of the RF time domain traces (Amplitude vs. Time, Frequency vs. Time or Phase
vs. Time). (MDO4000/B/C series models only.)
AUTO – specifies the currently selected waveform. The selected waveform can be
determined by querying SELect:CONTROl
Examples
CURSor:SOUrce CH3 sets the cursor source to Channel 3.
CURSor:SOUrce? might return AUTO, indicating that the cursor source has been
set to the currently selected waveform.
CURSor:VBArs? (Query Only)
Returns the current settings for the vertical bar cursors.
