Check whether the Trigger Mode is set to “Normal” or
“Single” and see whether the trigger level is out of the signal
range. If yes, set the trigger level in proper range by turning
the knob or pressing the 50% button. Or set the
Trigger Mode as “AUTO”. Moreover, push AUTO button to
display the waveform on screen.

knob to increase horizontal resolution to improve
the display.
(2) Maybe the display Type is set to “Vectors”, and set it to “Dots”
mode to improve the display.
