signal.
(4) 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.
(5) Change the trigger holdoff setting.
5. No display after pressing RUN/STOP:
Check whether 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 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 PictBridge 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.
