“edge” trigger mode. The video signal should use the
“Video” Trigger mode. The signal would display steadily
only when using matching trigger mode.
3. Attempt to change the “coupling” into “HF Reject” or
“LF Reject” display, so that the High/low frequency
noise will be filtered.
5. When pressing “RUN/STOP” button, nothing displays.
Check whether or not the trigger mode on the trigger
interface is in “normal” or “single”, and then check the
trigger level to see if it is over the waveform range. If yes,
please move the trigger level to the middle position or set
the trigger mode to the “Auto” position. You can also press
the “Auto” button to set it up automatically.
6. After the Acquisition is set to Averages or Display Persistence
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
slow. Turn the horizontal SCALE knob to increase
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.
