Scope

This standard specifies a simple method of measurement of resonance frequency and resonance resistance of quartz crystal units and describes a suitable measuring network. The measuring method and the network are suit- able for use over the frequency range 1 MHz to 200 MHz with a fractional frequency accuracy of the order of 10-6 with a reproducibility of 10-6 to 10-8 depending on the type of crystal unit being measured, and an accuracy of the measurement of resonance resistance of +/- 2% to +/- 5% depending on the accuracy of the voltage measurement.
