摘要
A method and system for generating a crystal model for a test product including a crystal oscillator are herein disclosed. The method includes measuring a first temperature of the test product and measuring a first frequency error of the crystal oscillator at a first calibration point during a product testing process, measuring a second temperature of the test product and measuring a second frequency error of the crystal oscillator at a second calibration point during the product testing process, estimating two parameters from the first temperature, first frequency error, second temperature, and second frequency error, and determining a 3rd order polynomial for the crystal model based on the two parameters.
