Measurement of quartz crystal unit parameters - Test fixture for surface mounted quartz crystal unitsWhat is BS EN 60444 8 Measurement of quartz crystal unit parameters about? BS EN 60444 8 is the eighth part of a multi series that covers the measurement of quartz crystal unit parameters. BS EN 60444 8 describes test fixtures suitable for leadless surface mounted quartz crystal units in enclosures as defined in IEC 61837. These fixtures allow the measurement of resonance frequency, resonance resistance, and equivalent electrical circuit parameters
