signal should use “Video” trigger. Only when the proper trigger type is used,
can the waveform be displayed stably.
(3) Try to change the Coupling to “HF Reject” or “LF Reject” to filter out the
high-frequency or low-frequency noise that disturbs the trigger.
(4) Change the trigger holdoff setting.
5. No display after pressing Run/Stop:
Check if the MODE at the trigger panel (TRIGGER) is on “Normal” or “Single”
and if the trigger level exceeds the waveform range. If yes, set the trigger level
to the middle or set the MODE to “Auto”.
Note that using the Auto button 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 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 through USB:
Check the IO Setting menu in UTIL to make sure whether the setting in USB
Device matches the currently connected device. If needed, restart the
oscilloscope.
8. The USB flash device can not be recognized:
(1) Check if the USB flash device can work normally.
(2) Make sure that the USB device being used is flash storage type. This
oscilloscope does not support hardware storage type.
(3) Make sure if the capacity of the USB flash device is too large. It is
recommended that the capacity of the USB flash device being used with this
oscilloscope is no larger than 4 GBytes.
(4) Restart the instrument and then insert the USB flash device to check it.
(5) If the USB flash device still can not be used normally, please contact
RIGOL.
