5. No display after pressing RUN/STOP:
Check whether the trigger mode in the trigger control area (TRIGGER) at the front
panel is “Normal” or “Single” and whether the trigger level exceeds the waveform
range. If yes, set the trigger level to the middle or press MODE and set the trigger
mode to “Auto”.
Note: Using AUTO could automatically finish the above setting.
6. The waveform displayed 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 the display Type to “Dots” to solve the
problem.
7. Digital waveform is not stable:
(1) Check whether the signal input from the selected trigger source is
synchronized with the digital signal.
(2) Adjust the oscilloscope to select the appropriate trigger mode, time base and
other general settings.
(3) If the display is still not stable, please check the electrical connections and
parameter settings again.
(4) Try to use other probe (such as analog probe) to verify the signal status of
the test point.
8. Fail to connect PC or printer through USB:
(1) Check the IO Setting in Utility to make sure whether the setting in USB
Device matches the device currently connected.
(2) Check whether the USB cable is properly connected to the oscilloscope and
PC.
(3) Check whether the USB cable is in good condition. If necessary, restart the
oscilloscope.
9. The USB storage device cannot 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 4 GBytes.
(4) Restart the instrument and then insert the USB storage device to check it.
(5) If the USB storage device still cannot be used normally, please contact
RIGOL.
