Measurement of quartz crystal unit parameters - Standard method for the determination of the load resonance frequency ƒL and the effective load capacitance CLeff using automatic network analyzer techniques and error correctionWhat is BS EN 60444 11 Calculating the effective load capacitance CLeff for quartz crystal units about? BS EN 60444 11 is the 11th part of a multi series standard used for the Measurement of quartz crystal unit parameters. BS EN 60444 11 defines the standard method of measuring load resonance frequency fL at the nominal value of CL, and the determination of the effective load capacitance CLeff at the nominal frequency for crystals with the figure of
