Chapter 5 Troubleshooting
The chapter lists the commonly encountered failures of DSG800 and their solutions.
When you encounter those problems, please solve them following the corresponding
steps. If the problem remains still, please contact RIGOL and provide your device
information (Syst  Information  System Info).
1. The screen of the RF signal generator is still dark (no display) after
the power key is pressed:
(1) Check whether the fan is running;
— If the fan is running but the screen is dark, the screen connecting wire
might be loose.
— If the fan is not running, the instrument does not start successfully and
please go to step (2).
(2) Check whether the power is correctly connected and whether the power
key is really on.
(3) Check whether the fuse is burned out. If the fuse needs to be replaced,
please contact RIGOL.
(4) Restart the instrument after finishing the above inspections.
(5) If it still does not work correctly, please contact RIGOL.
2. The screen is too dark and cannot be seen clearly:
(1) Check whether the brightness setting value of the LCD is too low.
(2) Press Syst  Display  Brightness and use the numeric keys or knob to
adjust the brightness of the LCD of the RF signal generator to a proper
value.
3. The RF signal generator is locked:
(1) Check whether the RF signal generator is in remote control mode (in remote
control,
is displayed in the status bar of the user interface). Pressing
ESC can exit the remote control mode and unlock the front panel.
(2) Check whether the RF signal generator is in local mode with the screen
being locked (when the screen is locked, front panel operations are not
available). Pressing ESC can unlock the screen and exit the locking state.
(3) If progress bar is displayed on the screen of the RF signal generator, some
operation is in progress. For example, when saving a file, the progress bar
will be displayed indicating that the save operation is in progress. During
the operation, the front panel is locked.
(4) Pressing Preset or restarting the RF signal generator can also unlock the
instrument.
