DISplay:XY {OF
F|TRIGgered}
DISplay:XY?
Related Commands
All CURSOR:XY commands.
Arguments
OFF – The channels are displayed indivi
dually as a function of time.
TRIGgered – The channels are displayed in “X-Y” pairs with CH1 being
displayed as a function of CH2, and so o
n.
Examples
DISplay:XY TRIG specifies to use the XY display mode.
DISPLAY:XY? might return OFF, indicating that the XY disp
lay mode is not
currently on.
DISplay:XY:WITHYT
Sets or returns the state of simultaneous display of the XY and YT waveforms
when in TRIGgered XY display mode. (To set the mode to TRIGgered XY
display, first use the command
:DISplay:XY TRIGgered.)
When both the XY and YT waveforms are displayed, the YT waveform is
displayed in the upper graticule, and the XY waveform is displayed in the lower
graticule.
This command applies to the MDO3000 and MDO4000C series only. For this
platform, the default state is 0 (XY display only)
.
For the DPO/MSO4000B and MDO4000/B platforms, this command is ignored
and the state is always 1 (to display both the XY an
d YT waveforms when in
XY display mode).
NOTE. For models with the DVM feature, such as the MDO3000 and MDO4000C,
this command does not take effect if the :DVM:DISPLAYSTYle is set to FULl,
but will take effect once the :DVM:DISPLAYSTYle is set to MINimum or if the
DVM is turned off.
