17.Display Control
You can set the type, persistence time,brightness of waveform,the grid type and grid
brightness of the screen display as well as the color display type of waveform.
17.1.To Select the Display Type
Press Display
→
display type to set the waveform display mode to "Vectors" or "Dots".
Vectors: the sample points are connected by lines and displayed. Normally, this mode can
provide the most vivid waveform to view the steep edge of the waveform (such as square
waveform).
Dots: display 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.
17.2.To Set the Persistence Time
Press Display
→
Persistence Time to set the persistence time of the oscilloscope to Min,
specific values (Min,1 s, 5 s,10 s and 30 s) or Infinite. In the following part, the frequency
sweep signal of a sine waveform is used to demonstrate the waveform effects in different
persistence times.
1. Min value
Enable to view waveform changing in high refresh rate.
2.Specific Values
Enable to observe glitch that changes relatively slowly or glitch with low occurrence
probability. The persistence time can be set to 1 s, 5 s ,10s and 30 s.
3.Infinite
In this mode, the oscilloscope displays the waveform newly acquired without clearing the
waveform acquired formerly. The waveform acquired formerly will be displayed in
relatively low-brightness color and the waveform newly acquired will be displayed in
normal brightness and color. Infinite persistence can be used to measure noise and jitter
and to capture incidental events.
17.3.To Set the Screen Grid
Press Display
→
grid to set the screen grid type.
Only show vertical and horizontal center grids.
Only show vertical and horizontal center grids, and use the dot display to draw other
horizontal and vertical grids.
Only show vertical and horizontal center grids, and use the line display to draw other
horizontal and vertical grids.
17.4.To Set the Waveform Brightness
Press Display
→
Waveform brightness, or in the case of non-menu operations,rotate V0
to adjust the brightness of the waveform of the channel.The default is 50%,the adjustable
range is 0-100%.
17.5.To Set the Grid Brightness
Press Display
→
Grid brightness to set the brightness of the screen grid, rotate V0 also
can adjust the grid brightness. The default is 50%,the adjustable range is 0-100%.
17.6.To Set the Screen Brightness
Press Display
→
Screen brightness to set the brightness of the screen, rotate V0 also can
adjust the screen brightness. The default is 80%,the adjustable range is 0-100%.
17.7.To Set the Color Mode
1.Color temperature mode
