CURSor:SOUrce?
Related Commands
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.

CURSor:VBAr
s:ALTERNATE<x>? (Query Only)
Returns the alternate readout for the waveform (Vbar) cursors specified by <x>.
This alternate readout is in effect when the selected waveform is a bus or digital
channel.

Syntax
CURSor:VBArs:ALTERNATE<x>?
Arguments
X=1specifies vertical bar cursor1.
X=2specifies vertical bar cursor2.
CURSor:VBArs:DELTa ? (Query Only)
Returns the horizontal difference between the two vertical bar cursors. The units
are specified by the
CURSor:VBArs:UNIts command.

Returns
<NR3>
Examples
CURSOR:VBARS:DELTA? might return :CUR SOR:VBARS:DELTa 1.0640E+00
indicating that the time between the vertical bar cu
rsors is 1.064 s.
CURSor:VBArs:HPOS<x>? (Query Only)
Returns the vertical value of the specified vertical bar ticks for cursor <x>.

Cursor
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.

CURSor:VBArs:UNIts
Arguments
<NR3> is a floating point number that specifies the cursor position.
Returns
A floating point value with an exponent.
Examples
CURSor:VBArs:POSITION2 9.00E-6 positions the cursor2 vertical bar cursor
at 9 ms.
