The commonly encountered failures of the analyzer and their solutions are listed
below. If the following problems occur, locate and resolve the problems according to
the following steps. If the problems still persist, contact RIGOL and provide your
instrument information to us. (For instrument information, press System → About
System → System Info.)
1． When I power on the instrument, the analyzer stays black and does
not display anything.
(1) Check whether the fan works normally.
— If the fan works normally, but the screen stays black, check whether the
connecting cable that connects the screen is loose.
— If the fan does not work normally, it indicates that the instrument has
failed to start up. Please handle it according to the method specified in
Step (2).
(2) Check the power source.
— Check whether the power supply has been connected correctly and the
power switch has been turned on.
— Check whether the fuse is burned. If you need to replace the fuse,
please use the specified fuse (AC 250V, T3.15A).
2． One or more keys on the keyboard does/do not respond, and stuck
keys are found.
(1) After you power on the instrument, check whether all the keys are
unresponsive.
(2) Press System → About System → Self Test → Keyboard, and check
whether there are unresponsive keys or stuck keys.
(3) If the above problems are found, check whether the keyboard cables are
loose or the keypad is damaged. Do not disassemble the instrument by
yourself, please contact RIGOL.
3． The spectral lines on the screen haven't been updated for a long time.
(1) Check whether the screen is locked or not. If yes, press Esc to unlock it.
(2) Check whether all the trigger conditions have been met and whether there
is a valid trigger signal.
(3) Check whether the analyzer is in single sweep.
(4) Check whether the set current sweep time is too long.
4． Errors or poor precision were found in the measurement results.
To calculate the system errors and check the measurement results/precision,
refer to the introductions in the "Specifications". To achieve the requirements of
the specifications specified in this manual, perform the following operations.

working normally.
