Normal phenomenon.

(1) Normal phenomenon. The horizontal time base might be too low. Increase
the horizontal time base to increase the horizontal resolution and improve
the display.

cause ladder-like display. Set the display Type to Dots to solve the problem.

Computer. If necessary, restart the oscilloscope.
