RIGOL Chapter 16 Display Control
16-2 DS8000-R User Guide
To Select the Display Type
Click on the function navigation icon
at the lower-left corner of the screen to
open the function navigation. Then, click on the "Display" icon
to open the
display setting menu. Click Type continuously to set the waveform display mode to
"Vector" or "Dots".
âš« Vector display: indicates that the sample points are connected by lines and
displayed. In most cases, this mode can provide the most vivid waveform for you
to view the steep edge of the waveform (such as square waveform).
âš« Dots display: displays the sample points directly. You can directly view each
sample point and use the cursor to measure the X and Y values of the sample
point.
To Set the Persistence Time
Click Persis.Time to set the persistence time for the oscilloscope. The available
values are Min, 100 ms, 200 ms, 500 ms, 1 s, 2 s, 5 s, 10 s, and Infinite.
The following part introduces the waveform effects of a Sine wave frequency sweep
signal in a different persistence time.
1. Min
Enables to view waveform changing in high refresh rate.
2. Specific Values
Enables to view glitches that change relatively slowly or glitches with lower
occurrence probability. The persistence time can be set to 100 ms, 200 ms, 500
ms, 1 s, 2 s, 5 s, or 10 s.
3. Infinite
In this mode, the oscilloscope displays the waveform newly acquired without
clearing the waveforms acquired formerly. The waveforms acquired formerly will
be displayed in relatively low-brightness color and the newly acquired
waveforms will be displayed in normal brightness and color. Infinite persistence
can be used to measure noise and jitter and to capture incidental events.
To Set the Waveform Intensity
Click Intensity, then use the pop-up numeric keypad or scroll with the mouse to set
the waveform intensity. The default is 50%, and the range available is from 1% to
100%.
