WebOct 2, 2015 · Drive level can be determined through simulation of the oscillator with the maximum expected value of R1 used in the crystal model. If a realistic model of the behaviour of the active section of the oscillator is not available then the current in the crystal should be measured using a high bandwidth current probe. WebCrystals below 30MHz are often specified at the fundamental frequency; above 30MHz they are typically specified as 3 rd, 5 th, or even 7 th overtone. (Overtones occur only at odd multiples.) Consequently, it is important to know whether the oscillator is operating in fundamental or overtone mode.
