Check whether or not the trigger mode on the trigger

the “Auto” button to set it up automatically.

time is set too long, the waveform refreshes slowly.
This is a normal condition for these settings.
7. The signal is displayed as a ladder-like waveform.
1. This phenomenon is normal. The time base may be too

horizontal resolution to improve the display.
2. Maybe the display Type is set to “Vectors”. You could
set it to Dots mode to improve the display.
