signal should use “Video” trigger. Only when the proper trigger type is used,
can the waveform be displayed stably.
(3) Change the trigger holdoff setting.
5. No display after pressing RUN/STOP:
Check whether the MODE at the trigger panel (TRIGGER) is on “Normal” or
“Single” and whether the trigger level exceeds the waveform range. If yes, set
the trigger level to the middle or set the MODE to “Auto”.
Note: using AUTO could automatically finish the above setting.
6. The display of waveform is ladder-like:
(1) The horizontal time base might be too low. Increase the horizontal time
base to increase the horizontal resolution and improve the display.
(2) If the display Type is “Vectors”, the lines between the sample points may
cause ladder-like display. Set Type to “Dots” to solve the problem.
7. Fail to connect PC or PictBridge printer through USB:
Check the IO Setting in Utility to make sure whether the setting in USB
Device matches the device currently connected. If needed, restart the
oscilloscope.
8. The USB storage device can not be recognized:
(1) Check whether the USB storage device can work normally.
(2) Make sure that the USB storage device being used is flash storage type.
This oscilloscope does not support hardware storage type.
(3) Make sure whether the capacity of the USB storage device is too large. It is
recommended that the capacity of the USB storage device being used with
this oscilloscope is no larger than 8 GBytes.
(4) Restart the instrument and then insert the USB storage device to check it.
(5) If the USB storage device still can not be used normally, please contact
RIGOL.
