Use a cap bridge or an LCR meter. Quadtech makes several models that will do this, and they have Labview drivers. What kind of single crystal are you measuring? There are standard settings(voltage and frequency) that should be used.
Could you tell me the detail about "Cap bridge" and what's LCR meter? the materials we are interested in is a small quarz disk( 10mm*10mm*0.5mm). thanks!
They are both test instruments that you connect to your crystal. The cap bridge typically only measures capacitance and dissipation at some discrete frequencies. An LCR meter will also measure inductance and impedance at a wider range of frequencies. The cap bridge is less expensive, and rather common. I have no experience with quartz crystals. Is it only capacitance that you need to measure?
