Patent Title: Calibrating high resolution measurements Abstract: There is described a method and system for calibrating measurements, in particular for calibrating a high resolution counter against an accurate real time calibrated clock signal. The method comprising obtaining the calibrated low resolution clock measurement and the corresponding high resolution counter measurement and calculating a range of possible corrections to the counter measurement to align it with the clock measurement. The correction range is adjusted to make it consistent with a previously stored correction range and a value is taken from it to calibrate the counter measurement. If the calculated range and the stored range are inconsistent then only the calculated range is used. A further measurement of the clock or counter is taken to double check. Notes: |
