Calibration
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—all possible combinations of vertical and horizontal settings are calibrated at the current
temperature. This calibration is valid for the current temperature ± 5° C and takes about 120 minutes.
Calibrate Current Setting—the oscilloscope is calibrated at the current vertical and horizontal setting.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.
