Syntax
CURSor:VBArs:HPOS<x>?
Related Commands
CURSor:VBArs:UNIts
Arguments
<x> specifies the cursor. Valid values are 1 and 2.
Returns
<NR3> is a floating point number that indicates the value of one of the ticks. The
units are the same as the selected waveform.
Examples
CURSor:VBArs:HPOS2? might return CURSOR:VBARS:HPOS2 100E-3,
indicating the waveform value where the cursor intersects it is 0.100.
CURSor:VBArs:POSITION<x>
This command specifies the horizontal position for the specified vertical bar
cursor. The cursor is specified by <x>, which can be 1 or 2. Values are with
respect to trigger position or the zero reference point for the designated waveform
(if horizontal units are not set to time). Use the CURSor:VBArs:UNIts command
to specify units.

Returns
A floating point value with an exponent.
Examples
CURSor:VBArs:POSITION2 9.00E-6 positions the cursor2 vertical bar cursor
at 9 ms.

POSITION1?
this command might return
:CURSOR:VBARS:POSITION1 1.0000E-06 indicating that the

Cursor
Syntax
CURSor:VBArs:UNIts {SEConds|HERtz|DEGrees|PERcent}
CURSor:VBArs:UNIts?
Arguments
SEConds sets the units of the vertical bar cursors for the time domain (seconds).
HERtz sets the units of the vertical bar cursors for the frequency domain (hertz).
DEGrees sets the units to degrees for measuring phase.
PERcent sets the units to percent for use with ratio cursors.
Returns
SECONDS, HERTZ, DEGREES,orPERCENT, depending on the current vertical bar
cursor units.
Examples
CURSOR:VBARS:UNITS HERtz sets the units of the VBArs cursors to 1/seconds.
CURSOR:VBARS:UNITS? might return :CURSOR:VBARS:UNITS SECONDS
indicating that the units for the vertical bar cursor are currently set to seconds.
CURSor:VBArs:USE (No Query Form)
Sets the vertical bar cursor measurement scale.
Conditions
This command is only applicable when ratio cursors are on.

Commands Listed in Alphabetical Order
Arguments
CURrent sets th
e V Bar measurement scale so that 0% is the current position of
the left-most V Bar cursor and 100% is the current position of the right-most
VBarcursor.
HALFgrat resets the ratio range to the default positions on the screen, half
of the number of horizontal divisions (five on the MSO/DPO4000B and
MDO4000/B/C), from 25% to 75% of the screen.
FIVEdivs sets V Bar measurement scale so that 5 screen major divisions is
100%, where 0% is -2.5 divisions and 100% is +2.5 divisions from the center
vertical graticule.
Examples
CURSOR:VBARS:USE CURRENT sets the V Bar measurement scale to use the
current cursor positions as 0% and 100% of scale if units are set to %.
CURSor:VBArs:VDELTa? (Query Only)
Returns the vertical difference between the two vertical bar cursor ticks.
Group
Cursor
Syntax
CURSor:VBArs:VDELTa?
Related Commands
CURSor:HBArs:UNIts
Returns
<NR3> indicates the vertical difference between the two vertical bar cursors' ticks.
Examples
CURSOR:VBARS:VDELTA? might return CURSOR:VBARS:VDELTA 1.064E+0,
indicating that the vertical difference between the vertical bar cursors ticks is
1.064 units.
CURSor:XY:POLar:RADIUS:DELta? (Query O nly)
Returns the difference between the cursors X radius and the cursor Y radius (ΔY¸
ΔX). The ratio is calculated as (cursor 2 Y - cursor 1 Y) ÷ (cursor 2 X - cursor 1 X).
