HDO4000 High Definition Oscilloscope
Calibration Settings
To ensure the instrument maintains specified performance, it is factory set to perform a calibration
during warm-up. We recommend that you warm up the oscilloscope for at least 20 minutes prior to use to
give the instrument time to complete calibration procedures.
Manually calibrate the oscilloscope when:
l
It is used in temperatures that differ from the previous calibration temperature by more than 5° C.
OR
l
It has been more than one month since the previous calibration.
Go to Utilities > Calibration Setup.
The Calibration dialog shows the oscilloscope's calibration status and recommended actions.
There are two options for this calibration: Calibrate All or Calibrate Current Setting.
l
Calibrate All—All possible combinations of vertical and horizontal settings are calibrated at the cur-
rent temperature. This calibration is valid for the current temperature ± 5° C and takes about 50 min-
utes.
l
Calibrate Current Setting—The oscilloscope is calibrated at the current vertical and horizontal set-
ting. This calibration is valid for this setting for the current temperature ± 5° C and takes under 30
seconds.
CAUTION. It is required that all inputs be removed from the oscilloscope prior to performing
calibration.
