2) Check whether it is a "false wave”: when the signal frequency is very large (more than
half of the sample rate), it is easy to appear as a "false wave". At this point, a small time
base should be set to make the sample rate more than 2 times the signal frequency.
3) Check the trigger type: general signals should use the “Edge” trigger and video signals
should use the “Video” trigger. Only when the proper trigger type is used, can the
waveform be displayed stably.
4) 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 touch screen does not respond to touch operation:
1) Check whether the Touch button backlight on the front panel is lighted up. If not, the
touch screen is not turned on. Press the button to enable the touch screen
2) Restart the instrument.
7. The USB storage device cannot be recognized:
1) Check whether the USB storage device can work normally.
2) Make sure whether the USB interface can work normally.
3) Make sure that the USB storage device being used is flash storage type. This
oscilloscope does not support hardware storage type.
4) Make sure that the U disk system format is FAT32.
5) Restart the instrument and then insert the USB storage device to check it.
6) If the USB storage device still cannot be used normally, please contact SIGLENT.
