Our practice is to test each crystal in several different types of oscillators. The finished crystal is subjected to mechanical stress and vibration, then tested again. The test oscillators have a frequency counter and an oscilloscope monitoring their outputs to display both frequency and the activity level of the crystal.
Defective items will be replaced at no charge.
