Syntax
DISplay:PERSi
stence {< NR3>|CLEAR|AUTO| MINImum|INFInit e}
DISplay:PERSistence?
Arguments
<NR3> 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. When persistence is set to infinite, it does not mean that the brightness
of any pixel should never decrease. The b rightness of a pixel is proportionally
dependent on the ratio between its intensity, which does NOT decrease at infinite
persistence, and the maximum value of intensity of any pixel on the screen. Thus,
if a particular pixel gets hit less often than o thers, its brightness will decrease over
time. It will become less bright relative to the pixels that get hit often.
AUTO specifi es that the oscilloscope automatically determines the
best waveform persistence based on the value of waveform intensity
(DISPLAY:INTEnsITY:WAVEFORM)
MINImum spec ifies that the wa ve form persistence is set to the minimum value
of 0.0E0.
Examples
DISPLAY:PERSISTENCE 3 specifies that the waveform points are displayed
fading for 3 seconds before
they completely disappear.
DISplay:STYle:DOTsonly
Turns on or off the dots-only mode for the waveform display.
