A method and apparatus for calibrating an oscilloscope and storing the calibration results for further use. Accordingly, an oscilloscope is provided with a calibration cache database for storing various calibration curves and their associated states. Each time the oscilloscope is calibrated, the resulting calibration curves are stored in the cache. When the oscilloscope returns to a previously calibrated state, the corresponding calibration curves are simply loaded from the cache to recalibrate the oscilloscope. After some period of use, many or most states for the oscilloscope will have entries in the database, and revisiting these states for the oscilloscope will have entries in the database, and revisiting these states will no longer require recalculating the calibration curves. |
