IEC TR 60444-4:1988 ED1

Measurement of quartz crystal unit parameters by zero phase technique in a pi-network. Part 4: Method for the measurement of the load resonance frequency fL, load resonance resistance RL and the calculation of other derived values of quartz crystal units, up to 30 MHz IEC TR 60444-4:1988 ED1

Scope

Specifies a simple method of measuring load resonance frequency. The method uses the change in resonance frequency which occurs when a load capacitance is inserted in series with the crystal unit.
