BS EN 60444 9 is the ninth part of an international standard that focuses on the measurement of quartz crystal unit parameters. BS EN 60444 9 describes two methods for determining the spurious (unwanted) modes of piezoelectric crystal resonators. It specifies the following methods: Method A i. e., full parameter determination, which allows the determination
