Syntax
DISplay:INTENSITy:WAVEform <NR1>
DISplay:INTENSITy:WAVEform?
Arguments
<NR1> is the waveform intensity and ranges from 1 to 100 percent.
Examples
DISPLAY:INTENSITY:WAVEFORM? might return
DISPLAY:INTEnsITY:WAVEFORM 60
as the intensity of the waveforms.
DISplay:PERSistence
This command specifies the display persistence for analog waveforms. This
affects the display only.
Group
Display
Syntax
DISplay:PERSistence {<NR3>|CLEAR|AUTO|INFInite|OFF}
DISplay:PERSistence?
Arguments
<NR3> is a floating point number that specifies the time of the persistence.
CLEAR resets the persist time count down and clears the display of acquired points.
INFInite displays waveform points until a control change resets the acquisition
system.
NOTE. When persistence is set to infinite, it does not mean that the b rightness
of any pixel should never decrease. The brightness of a pixel is proportionally
dependent on the r atio between its intensity, which does NOT decrease at infinite
persistence, and the maximum v alue of intensity of any pixel on the screen. Thus,
if a particular pixel gets hit less often than others, its brightness will decrease
over time. It will become less bright relative to the pixels that get hit more often.
AUTO specifies that the oscilloscope automatically determines the
best waveform persistence based on the value of waveform intensity
(DISplay:INTENSITy:WAVEform)
OFF turnsoffDPOmode(0secondsofpersistence).
