Self Test and Self Calibration
The arbitrary/function generator performs a limited set of hardware tests at power-on. You can also perform the manual
diagnostics and/or self calibration using the Utility menu.
■ Diagnostics (Self test) – Perform the self test to verify that your instrument is operating correctly.
■ Calibration (Self calibration) – The self calibration mainly checks DC accuracy using the internal calibration routines.
Quick Tips
■ Before executing self calibration, ensure that the ambient temperature is between +20 °C and +30 °C (+68 °F to
+86 °F). Allow a 20 minute warm-up period before executing self calibration.
■ Disconnect all the cables from the instrument when you perform self test or self calibration.
■ Perform self calibration at least once a year to maintain DC accuracy. It is recommended that the self calibration should
be performed along with a periodic check.
NOTE. If you need to verify that the instrument meets the warranted specifications, do the complete set of performance
verification procedures provided in the Service Manual.

CAUTION. Do not power off the instrument while executing self calibration. If the power is turned off during self calibration,
data stored in the internal memory may be lost.
