4. Wrong measurement results or poor precision:
To calculate the system errors and check the measurement results and precision,
refer to the introductions in “Specifications”. To reach these specifications,
please:
(1) Check whether all the external devices are successfully connected and are
working normally.
(2) Get some knowledge of the signal under measurement and set appropriate
instrument parameters.
(3) Make measurements under proper conditions; for example, warm-up the
instrument appropriately and operate the instrument under the specified
environment temperature.
(4) Calibrate the instrument regularly to reduce or avoid errors that might
occur over time.
— If you need a specific calibration after the stated calibration period,
contact RIGOL or get paid service from authorized measurement
agencies.
— The analyzer provides auto calibration function. If required, press
System Calibrate Self-Cal and select “On”. The instrument
will perform self-calibration regularly. Within half an hour after
power-on, the analyzer executes a self-calibration every 10 minutes
and per hour after being powered on for more than half an hour.
— Press System Calibrate Cal Now to make a self-calibration
immediately.
5. Pop-up Message:
The instrument may display prompt messages, error messages or state
messages according to the current working status. These messages are
displayed to help you to use the instrument correctly and are not instrument
failures. For information of the pop-up messages, please refer to
“Messages”.
